DNA Essay example - 1427 Words

DNA is a term that has been used in science as well as in many parts of daily life. The general public knows that DNA is a part of our bodies but they may wonder what exactly is DNA? DNA is a term used for deoxyribonucleic acid and it is the genetic material of all organisms, it is the molecule of life and it determines all of our physical characteristics. DNA is present in every single form of life. More than 50 years after the science of genetics was established and the patterns of inheritance were clarified, the largest questions remained unanswered: How are the chromosomes and their genes copied exactly from cell to cell, and how do they direct the structure and behavior of living things? Two American geneticists, George†¦show more content†¦Ã¢â‚¬Å"To make a new, identical copy of the DNA molecule, the two strands unwind and separate at the bases which are weakly bound; with more nucleotides available in the cell, new complementary bases can link with each separated strand, and two double helixes result.† (Caldwell) Since the â€Å"backbone† of every chromosome is a single long, double-stranded molecule of DNA, the production of two identical double helixes will result in the production of two identical chromosomes. The DNA backbone is actually longer than the chromosome but is tightly coiled up within it. This packing is now known to be based on minute particles of protein known as nucleosomes, that can only be seen under the most powerful electron microscope. The DNA is wound around each nucleosome to form a beaded structure. The structure is then further folded so that the beads associate in regular coils. Thus, the DNA has a â€Å"coiled-coil† configuration. After the discoveries of Watson and Crick, the question that remained was how the DNA directs the formation of proteins, compounds central to all the processes of life. Proteins are not only the major components of most cell structures, they also control virtually all the chemical reactions that occur in living matter. The ability of a protein to act as part of a structure, or as an enzyme affecting the rate of a particular chemical reaction, depends on its molecular shape. This shape, in turn,Show MoreRelatedDna Analysis On Dna And Dna1535 Words   |  7 PagesIntroduction DNA stands for deoxyribonucleic acid. DNA is the genetic material of life and is made up of monomers called nucleotides. Nucleotides are monomers made up of a phosphate group, a sugar, and a nitrogenous base. (Freeman, 2014) The way that DNA is able to store information is in its nitrogenous bases. There are four different types of nitrogenous bases that DNA strands contain: adenine (A), guanine (G), cytosine (C), thymine (T). These nitrogenous bases in DNA are each different,Read MoreDNA Adaptation In DNA1746 Words   |  7 Pageshuman body operates is due purely to one’s genetic disposition. This is due to the way proteins are produced. In protein production, DNA is read three base pairs at a time making up for a codon which codes for a specific amino acid.

Naturalistic Observation Of Student s A Coffee Line

Naturalistic Observation of Student’s in a Coffee Line In the United States, 85% of adults own a cell phone, with 18 to 24 year olds texting the most (Zickuhr, 2011). Of these adults, 67% reported that they check their phone even if they do not hear it ringing, 44% sleep with the phone beside their bed, and 29% reported they could not live without their cell phone (Smith, 2012). In addition, according to the Baylor University report, studies show that young adults check their phone an average of 60 times a day. This study examined cell phone use among university students that were alone and in a group. Specifically, we were interested in observing whether students alone in a coffee line or students in a group in a coffee line, spent more or less time on their cell phone. We were also interested to observe if gender affected cell phone usage and whether males or females were more likely to be in a group. The purpose of this study was to determine if university students that are alone spend more or less time on their phone than students that are in a group. We also examined if gender was an important factor on whether a student was in a group or alone. Using naturalistic observation, we calculated the amount of time individual students were on their phone per three minute time interval. The hypothesis was that students alone in a coffee line would spend the most time on their phone. We also predicted that women were more likely than men to be in a group.

Teacher’s Pay for Performance Free Essays

Should Teacher’s Salaries Be Based on Student’s Academic Performance? Is a student’s failure in a class an indication that a teacher or professor did not adequately perform his or her job? There are two points of view on this issue. Many will argue that teachers should be paid on a merit system, or Pay for Performance system. There are some that believe that there are too many external factors in a class room for a teacher’s salary to be based on how he or she performs in the class room. We will write a custom essay sample on Teacher’s Pay for Performance or any similar topic only for you Order Now Teacher’s pay for performance will be highlighted by first discussing what is pay for performance, next, detailing the definition of teaching, and finally, exploring the question of should teacher’s salaries be based on a student’s academic performance. Pay for performance is essentially when an employee is allowed to be partly responsible for his or her pay increase. A company will set goals as well as allow the employee to set his or her own goals and if the employee meets those goals, he or she will get a raise. These raises are based on levels of performance ranging from one to five. A level of one means that an employee failed to meet his or her expectations. A level of two means that an employee needs improvements in some areas. A of three means that an employee met his or her expectations. A level of four means that an employee exceeded his or her expectations. A level of five means that the employee far exceeded his or her expectations or as some managers imply, he or she is a â€Å"super employee†. Pay for performance is designed to inspire employees to work harder so they can obtain higher raises and bonuses if they reach a certain level. Employees may also be motivated to perform better the next year. The question remains, should teachers be on this type of merit system? Teaching is conveying knowledge in formal learning institutions, whether it is a school, K-12, or a university or college. Teachers have a major influence on a student’s life. They plant seeds of knowledge that continue to grow with a student. They support, empower, engage and care for their students. Today, most teachers are paid based on their seniority or academic degrees. Perhaps they should be paid based on their level of accomplishment and responsibility. Teacher evaluations should be based partly on student achievement data and their raises should be based on student’s academic performance. If teachers were paid based on student’s academic achievements, they would put forth more effort to provide a higher quality of teaching. Competition would be raised among teachers and a possibility of higher salaries would encourage them to perform better. If teachers were paid for their performance it might also differentiate teachers who care about their student’s performance from those who only want to collect a paycheck. On the other side of the coin, there are also reasons why a teacher’s salary should not be based on student’s academic performance. The first being that there is a lack of standard academic performance tests, which means there is no measurement criteria. There is the possibility that some teachers might give students higher grades to benefit their salaries. The strongest argument against teacher pay for performance would be that all students do not have the same level of intelligence, commitment, or determination. It may not be fair to hold a teacher responsible for a student that cannot learn or do not want to learn. Given the scenario that a teacher’s pay increases would be based on student’s academic performance, their levels of performance could range from one to five also. A level five would indicate that all students have passed the class with a grade of B or better and performed well on a standardized test. A level four would indicate that all students passed the class with a grade of C or better. A level three would indicate that 80 percent of the students passed the class. A level two would indicate that at least 50 percent of the students passed the class. A level one would indicate that only 20 percent of the students passed the class or a student has failed the class more than once under the same teacher. Teachers that perform at level one should not receive pay increases. A performance level of three or above should receive salary increases. An example of a level one performance would be if a student failed the same class two or more times or if only four out of twenty students passed a class, then that teacher or professor obviously has not imparted the knowledge to their students that they set out to convey. An example of a level three teacher’s performance would be if his or her students continuously increase their academic performance or pass standardize tests. In conclusion, I assert that teacher’s salaries should be based on their student’s academic performances. If teachers hit their levels, they should receive higher raises. It they fail their students, their salary should not increase. There are a lot of educators that would disagree with this assertion; however, given the state of our education system, a change needs to be put in place. If teachers are required to perform better and are paid better based on their performance, then students will perform better. How to cite Teacher’s Pay for Performance, Essay examples

In the same year, Jackie also played track, basketball, and baseball. He was the first student at UCLA to play on four varsity teams in the same year. In 1944, when Jackie was discharged from the army, he started to play baseball professionally.This is when Jackie Robinsons career as a professional baseball player began. When you think of baseball in the sasss, Jackie Robinsons name probably comes to mind. Jackasss career officially started when he began his training with the Montreal Royals in 1946.

This led to Jackie being approached by the Brooklyn Dodgers president, Branch Rickety, in 1947.His first game on the Dodgers marked the first time that of African American played Major League Baseball. Even after Jackie died on October 24th, 1972, his long, legendary career lives on through Major League Baseball.

Jackie Robinson was an outstanding baseball player and by playing baseball, he was able to change the nation. Although Jackie Robinson contributed a lot to the sports field, he was also n active member of the civil rights movement.A lot of people have learned about when Rosa Parks was arrested for refusing to give up her seat in the front Of the bus to a white man, but not many people realize that Jackie Robinson did the same thing. Jackie was forced to face the court-martial because he refused to sit on the back of the bus. He did this to stand up for himself and black rights. The court-martial acquitted him of the charges. He was also a participant in charity work. Charities that helped black families in poverty were a high priority for Jackie Robinson. This was important to Jackie because when he was growing up his family was very poor with little opportunities as the minorities in their communities. These charities contributed to the civil rights movement by bringing attention to the poverty spread throughout black areas of society. The most important thing that Jackie Robinson did for civil rights was support Governor Rockefeller campaign. Governor Rockefeller wanted civil rights for all and make segregation a thing of the past. His work towards the civil rights movement shows that Jackie Robinson did a lot for the nation.There is no doubt attacked Robinson is a legendary African American. If it wasnt for his contributions to the sports industry and to the civil rights movement, integration would not be how it is today. Jackie Robinson was a legend in the making growing up in Cairo, Georgia. He played on four varsity teams in the same year at UCLA and then was the first Black Major League Baseball player, After playing baseball, Civil rights became a priority in Jackasss life. For all of these reasons and many more, Jackie Robinson should be included in an exhibit in our museum.

Cellular phone as a help to it essays

Cellular phone as a help to it essays Communication between one place and another has always been a problem, but as technology advances, the telephone has been developed to allow users to be able to communicate with each other over long distances. But the telephone does not permit users to utilize it outdoors since it is tied down by phone lines, so a technology-the cellular phonewas invented for better mobility. Cellular phones have changed our lives dramatically. They provide us with extra safety and comfort and with the immediate ability to call 911 in the event of trouble, as well as give us discreet access to contact in case of personal danger. Cellular phones offer the ability to reach out for help from any place and at any given time. There is no doubt that wireless devices are becoming increasingly popular and more and more intelligent. Recently, there are controversies over the purpose and use of the cell phone, some disagree and dislike the fact that cell phones are used while people are driving or at school; t herefore, bans have been imposed. However, one must take into account the security a cell phone provides to its user in cases of emergency. It is much faster and more efficient to call for help; the cell phone saves time to call for help, and ultimately helps saves time and lives. Cell phones are more a help than a hazard, and are not dangerous at all; in fact, they provide necessary usage and safety to their users. The first telephone was invented on March 10, 1876 by Alexander Graham Bell. Since then the basic concept of the telephone was further enhanced in 1947 and has continuted to develop into what it is today. The creation of the telephone then led to the invention of the more mobile and verisitile version of itthe cellular phone. As a direct result of the telephone, the Internet was later created in the late 1970's. The cellular phone has helped shorten communication barriers through the utilization of wireless waves...

Validez en EE.UU. de matrimonio celebrado en otro país

Validez en EE.UU. de matrimonio celebrado en otro paà ­s Estados Unidos reconoce como vlidos los matrimonios celebrados en otros paà ­ses siempre y cuando cumplan todos los requisitos exigidos por la ley que aplica en el lugar de la boda. Esto aplica tanto a matrimonios entre una mujer y un varà ³n como a la unià ³n entre dos personas del mismo sexo. Como consecuencia de este reconocimiento de la validez del matrimonio celebrado fuera de EE.UU. se derivan dos efectos. En primer lugar, si una persona que se casà ³ en otro paà ­s desea contraer un nuevo matrimonio deber ser viuda, anular su divorcio o proceder a divorciarse, lo cual puede hacer aà ºn cuando no tenga nacionalidad estadounidense y matrimonio se hubiera celebrado en otro paà ­s. En segundo lugar, por matrimonio como ciudadano estadounidense o residente permanente legal es posible emigrar a los Estados Unidos sacando una tarjeta de residencia conocida como green card si cumple con todos los requisitos que exige la ley migratoria. Puntos clave: validez en EE.UU. de matrimonio celebrado en otro paà ­s Si el matrimonio es vlido segà ºn la ley del paà ­s en el que se celebra, es vlido en EE.UU.Los oficiales consulares de EE.UU. no celebran matrimonios.El matrimonio con ciudadano o residente, por sà ­ mismo, no da derecho a emigrar a EE.UU.Para emigrar a EE.UU. por matrimonio, el ciudadano o residente debe pedir a su cà ³nyuge Respeto por las leyes locales que regulan el matrimonio Para que Inmigracià ³n de Estados Unidos reconozca como vlido a un matrimonio celebrado en el extranjero, à ©ste debe ajustarse a la ley local del lugar en el que la pareja se casà ³. Hay que tener en cuenta que en algunos paà ­ses se exige a los dos novios tener la residencia allà ­ para poder casarse. Adems, si uno de los contrayentes es menor de edad se va a pedir algà ºn tipo de autorizacià ³n de los padres o tutores. Incluso en algunos paà ­ses se exigen determinados anlisis de sangre, requisito que hay que cumplir si es que asà ­ se pide legalmente. Ya que para que EE.UU. reconozca como matrimonio vlido que cumpla con las leyes locales, en el caso de parejas gays es imprescindible celebrar la boda en un estado o en un paà ­s donde es legal. Si no se hace asà ­, no tendr efectos migratorios. En otras palabras, el ciudadano o residente no podr pedir los papeles para su cà ³nyuge, porque EE.UU. considera que no estn casados legalmente. Problemas del matrimonio por poderes para Inmigracià ³n Si la intencià ³n es pedir la tarjeta de residencia permanente para el cà ³nyuge extranjero, se recomienda no casarse por poderes. Las leyes migratorias de EE.UU. exigen que el matrimonio se consume antes de aprobar cualquier peticià ³n por esta causa. Los matrimonios por poderes pueden crear la sospecha de que matrimonio no se ha consumado o que se trata de un matrimonio de conveniencia para sacar los papeles. Documentos  para casarse fuera de EE.UU. El ciudadano estadounidense que se casa en el extranjero deber probar quià ©n es mediante  una identificacià ³n con foto, generalmente el pasaporte americano vigente. Adems es normal que se pida documentacià ³n adicional, como copia de la partida o certificado de nacimiento. Si el contrayente ha estado casado previamente  deber presentar la sentencia del divorcio o la nulidad o el certificado de viudedad. Hay que tener en cuenta que posiblemente se pida que estos documentos sean traducidos al idioma del paà ­s en el que tendr lugar la ceremonia. Por otra parte una vez celebrado el matrimonio fuera de los Estados Unidos ser necesario traducir al inglà ©s el certificado de matrimonio para su uso migratorio. La  traduccià ³n puede hacerla cualquier persona con un conocimiento fluido del inglà ©s y del otro idioma y se necesita certificar la traduccià ³n, lo cual puede hacerse siguiendo un modelo de carta. Autentificacià ³n de documentos de matrimonios celebrados en el extranjero Dependiendo del uso que se quiera dar dentro de Estados Unidos al certificado de matrimonio de celebrado en otro paà ­s es posible que se necesite una autentificacià ³n, que puede ser de dos tipos. En primer lugar, un sello que se conoce como  apostilla de la Haya. La mayorà ­a de los paà ­ses de habla hispana forman parte del Convenio de la Haya y ese sello es el que se necesita para legalizar el certificado de matrimonio que se desea utilizar en Estados Unidos. En segundo lugar, para los paà ­ses que no forman parte de este convenio ser necesario obtener una certificacià ³n de legalidad. Cabe destacar que, para trmites con el Servicio de Inmigracià ³n y Ciudadanà ­a (USCIS, por sus siglas en inglà ©s), por regla general es suficiente una traduccià ³n certificada y no se exige la apostilla de la Haya.  ¿Bodas en embajadas y consulados  de EE.UU.? Ni los cà ³nsules ni ningà ºn oficial de las oficinas diplomticas de los Estados Unidos est autorizado para celebrar bodas en el extranjero. Por ello, sà ³lo en casos muy excepcionales es posible que un matrimonio tenga lugar en el edificio de una embajada o un consulado. Sin embargo, en algunos casos los consulados sà ­ que prestan un servicio necesario cuando algunos paà ­ses se exige por parte del contrayente extranjero una declaracià ³n jurada de que tiene la capacidad legal para contraer matrimonio. Este tipo de declaraciones se pueden prestar ante un oficial consular americano que tienen poder para actuar como notarios pà ºblicos en el extranjero. Traer al cà ³nyuge extranjero a vivir a Estados Unidos El matrimonio con un ciudadano americano o residente, por sà ­ solo, no da derecho a viajar a Estados Unidos ni a permanecer en el paà ­s para a vivir y trabajar. Si la intencià ³n del nuevo matrimonio es vivir en EE.UU, el cà ³nyuge estadounidense o el residente permanente debe pedir una tarjeta de residencia por matrimonio para su esposo o mujer y tambià ©n para los hijastros, si se cumplen condiciones estrictas de edad. Adems, los ciudadanos estadounidenses –pero no los residentes– tienen la opcià ³n de solicitar una visa K-3  para su cà ³nyuge y una K-4 hijos o hijastros en vez de seguir el proceso ordinario de peticià ³n de cà ³nyuge. En realidad estas son unas visas muy poco utilizadas y solo son convenientes cuando los plazos de tramitacià ³n de la peticià ³n ordinaria de la green card para cà ³nyuge de ciudadano son muy largos. En estos casos siempre es mejor estar aconsejado por un abogado migratorio. En los casos de cà ³nyuge extranjero fuera de EE.UU. y ciudadano o residente en los EE.UU. existe la tentacià ³n de que en vez de iniciar un proceso de peticià ³n de la green card el cà ³nyuge extranjero ingrese como turista a los Estados Unidos y luego solicitar un ajuste de estatus para obtener la green card. Esa opcià ³n no es la correcta desde el punto de vista migratorio y puede dar lugar a que no se le permita el ingreso al paà ­s y se le expulse en el puesto de control migratorio o, si consigue ingresar, no se le apruebe la peticià ³n de green card. Esto es asà ­ porque se puede considerar que ingresà ³ al paà ­s en fraude de ley al utilizar un estatus de turista cuando su intencià ³n era ingresar a EE.UU. para quedarse. En estos casos la intencià ³n es fundamental y es recomendable aconsejarse con un abogado para evitar problemas con el USCIS cuando se presente la solicitud de la green card. Finalmente, cabe destacar que en los casos en los que el  ciudadano  que desea traer a vivir a Estados Unidos a su esposo extranjero puede tener problemas muy particulares si el estadounidense siempre o en los à ºltimos aà ±os ha residido fuera de los Estados Unidos. El problema es que podrà ­a ser difà ­cil probar medios econà ³micos suficientes para patrocinar, tal y como lo pide la ley. Adems, para pedir los papeles se exige que el patrocinador resida o tenga como residencia principal los EE.UU. Condicionalidad de la green card En muchos casos, la green card que se obtiene por matrimonio con un ciudadano es condicional por dos aà ±os. Es lo que se conoce como CR-1. En estos casos se exige activamente levantar la condicionalidad.  Esto ocurre cuando la residencia se otorga antes de que la pareja lleve dos aà ±os de casados. Por el contrario, si el cà ³nyuge extranjero de un ciudadano obtiene su tarjeta de residencia despuà ©s de haber cumplido el segundo aniversario de casado su visa de inmigrante es una IR-1 y es definitiva, es decir, no necesita levantar ninguna condicionalidad. Matrimonios de conveniencia Las autoridades migratorias son conscientes de que a veces los matrimonios son una farsa y su à ºnico objetivo es obtener la green card. Cuando se llega a esa conclusià ³n puede haber consecuencias serias. Adems, durante la tramitacià ³n de los papeles puede suceder que se lleven a cabo investigaciones para intentar determinar si el matrimonio es real y siempre existe el riesgo de una denuncia anà ³nima sobre la finalidad del matrimonio. Test de respuestas mà ºltiples Para entender la green card, cà ³mo obtenerla, obligaciones, derechos, cà ³mo conservarla y cà ³mo es posible perderla por cancelacià ³n es importante tener los conocimientos bsicos.   Este test de respuestas mà ºltiples es muy aconsejable ya que el conocimiento evita meterse en problemas de los que luego es difà ­cil salir. Este es un artà ­culo informativo. No es asesorà ­a legal.

Management research methods Assignment Example | Topics and Well Written Essays - 2500 words

Management research methods - Assignment Example However, from the point of view of the consumers, it is of vital concern that the personal motivations that prompt them to make better use of the internet as shopping venue be ascertained. While many, if not all, the products sold online are also available from brick and mortar stores and other conventional venues such as through the televised home shopping network, the motivations for customers to purchase online appears to be influenced by a special set of factors which pertains exclusively to the online technology. The individual must have a strong sense of confidence in trusting the system, because (1) he/she has not physically examined the product he/she is actually buying, only being able to view a product replica on his/her monitor or screen; (2) he/she is transacting with a business entity he/she only sees onscreen, and which may be located elsewhere on the globe. Without a physical store to go to, he or she may not know how to reach the vendor if his/her claim is unsatisfied ; (3) the customer has to have his/her payment transmitted before delivery of the purchased item, thus sending the cash through electronic means is a leap of faith; and (4) release of the customer’s bank account or credit card number is a risky act which may be the source of identity fraud and electronic theft.

The survey should therefore aim for a large number, and from observing the sample sizes shown in the different academic studies, a good number would be 250 to 350 respondents. It is also important to make sure that the locations surveyed represent as equal ly as possible all the area intended to be covered by the study. The sample selection method must ensure the highest chances of getting a representative sample, while ensuring that the intended respondents are reached and their existence and qualifications verified. Inasmuch as those who are qualified to respond to this survey are those who are exposed to and confident
