Dna Fingerprinting Essays - Molecular Biology, Biometrics

Dna Fingerprinting Essays - Molecular Biology, Biometrics Dna Fingerprinting DNA Fingerprinting DNA Fingerprinting is also referred to as DNA profiling and DNA typing. It was first developed as an identification technique in England in 1985. The original use was to expose the presence of any genetic diseases. About three years later it became used to identify criminals through the analysis of genetic material and to settle paternity disputes. It is still used for those reasons today. The DNA fingerprinting process is called gel electrophoresis. It is a process that can sort pieces of DNA according to its size. The process is done by taking samples of DNA from the crime scene and comparing it with samples from the accused. Samples are taken from biological materials like blood, semen, hair, and saliva. In the testing process the DNA samples are first entered into the wells in a gel like substance called Agarose. The gel is placed between two electrodes, one negatively charged and the other positively charged. The wells in the Agarose are inserted on the negative side because DNA has a negative charge. Molecules of DNA then travel in lanes toward the positive side. Small molecules will travel farther than the bigger ones, because they have an easier time moving through the gel. So the molecules will then be assorted according to their size. Next, the gel is X-rayed to see the parallel bands (showed by black bars on the film) in each lane. The separated molecules of DNA form a pattern of parallel bands that show the structure of the DNA. The pattern should never change for one person. In a court of law, the results of a DNA fingerprinting examination can be used to convict or acquit an accused person. If the accused's DNA matches the one at the crime scene then that person could be convicted. Critics believe that a DNA fingerprint may not yet be reliable enough to use in the court system. They question how accurate a DNA fingerprint is and the cost of it. They believe that it is not very accurate because only a segment of DNA is used and not the complete strand. A DNA fingerprint may not be unique. The confirmation of the uniqueness has not been confirmed yet. Also the process is done in private laboratories so the exact testing standards may not be followed and standardized quality controls may not be used. Human error can have false results if they do not use the exact testing standards with quality controls. The testing is very expensive and if the accused can't pay for the testing then they will not be able to defend themselves using the results of the test. Also a question is, will people misuse the process? A misuse that scares them is the unauthorized use of the database that will be created with the increasing use of the DNA fingerprint. An example of an unauthori zed use is identifying individuals with a genetic disease by looking up their personal profile without their permission. Cases Katie Hoskins at the age of 15 found the body of her murdered mother, Glenda Hoskins, inside a rolled up carpet in their loft.

K pop - Essay Example This suggests that there are versions of Asian elements that they have retained in their Western style. At some point, it gets fuzzy whether they are modifying their Asian style or articulating Western elements to fit into traditional Asian performances.

In this sense, the song is similar to K-pop’s songs that the band composes in Korean but it stages in Hip Hop style (Seabrook 1). This sums up the idea of cultural technology. The Asian entertainment industry is refurbishing its outlook in order that it attracts the whole world. In order to attract the whole world the entertainers have to curve way of reaching audiences.

English Language Learner Essay

The United States still represents to the rest of world a land of opportunities. Immigration occurs when people from all part of the world make their way here to start new lives, find their new jobs or build new homes. Some leave their country to flee from oppression and injustice. Some want a life to escape poverty. Now the English Language Learners in America school constantly growing percent of all U.S student-There are more than five million children who are English Language Learners (ELLs). Research show that Bilingual Education is beneficial to people who learning English to support their English Language also native language and to retain. The Bilingual Education is more effective to English Learners research that students who are educate in Bilingual classrooms do as well as or better than the groups of English sold literacy skill, cause of their thinks are just would cover their miserable life by money, that’s all they have to do. The challenge faced by English Language is an obstacle to their education success in this country. Amount of students who participating to learn English are enrolled in U.S. public schools (pre-K-12) increased by 8.5 percent, from 46.0 million in 1997-1998 to mostly 50 million in 2007-2008. In them, at least 10.7 percent or more than 5.3 million children were English Language Learners (ELLs). Over the time, the number of ELL increased by 53.2 percent, from 3.5 million to 5.3 million) in the same period, this statistic was show that there is no signal to stop and might be grow up in the future. The nation’s ELL student (about 1.5 million children) mainly lived in California, state with the largest amount of student in need of English instruction. Behind California, the three states also contained an amazing number of ELL enrollment: Arizona (166,572), New York (213,000), and Texas (701,800). All English Language Learners are definitely struggling to learn English sometime, they were fail to understand what is the teacher talking about, and may become unpleasantness when they have an idea but cannot transmit wholeness express their thoughts in English. That’s might be a biggest problem for ELLs who would like to speak English well but don’t want to learn English. Meanwhile, many students experience another kind of struggle, when they go home, they speak different language in which their parents  communicated. But a lots immigrant students of ELL have a habit of fluency in English and so want to give up their native language. They pressure to speak English at school; they are expected to speak their native language at home. In the education process, there is â€Å"English-only Laws do not help Immigrant gain fluency in English â€Å". Some individually consider that being not only of English Language Learners (ELL), but of American communities as a whole. The governments do not promote English as official language so much as they make discrimination to different kind of language. However, ELLs should not receive English-only laws, instead achieve literacy, it makes disconnect to immigrant who want to keep their tradition. Beside of that, an obstacle for all students of ELLs that they must to receive the same program such as student spokes of native English when they are during education process, many trammels as reading literature in English cause most literature is culture bound. Students who desire to speak English fluency must struggle for several year before they understand everything that is said i n their classroom, and that is discrimination for all ELLs as they received entire subjects with not their language such as mathematics, science, social study, language art,†¦ while their literacy skills do not well at all. Bilingual Education – consider that such as education in an English-language school system in which students with little fluency in English are taught in both their native language and English. Research show that Bilingual Language is the effective choice and definitely benefic for English Language Learners. It not only helping to advantage of ELLs to become solid literacy skills with both language, Bilingual Education also support to students develop ability of communication with international. The review found that almost K-12 students show who have been educated in bilingual classroom, enroll in programs that have high level of bilingualism probably do as well as or might be better than comparison group of English Learners in English-only program. English Learners want to improve their English as well as they could be, but they also receive a lot of challenges from English. As you are learning any new language, it takes a lot of dedication, practice and time. But all of that will pay off when you are able expressing yourself in an exciting way. You have to know what is your first step will going to be, then just keep going and expand all experience that you have become perfectly. Also, the English teacher should  purposefully select words and sentence structures that will help students learn rather than hinder their success in class or practice for them to listening, specific is talking to improve their pronunciation. Eventually, English Language Learners could be received a lot of challenges by English Language as they struggle to fit into a new society, learn a new language, improving the achievement of communicate ability with international. However, English has been the common world-wide language, and it will be in the future. For this reason, English Language Learners must be insist that practice and policy by based on the best evidence we have and not on politics or predilections.
