Human Genetic Screening Essay -- Science Genes DNA Essays

Human contagious ScreeningHuman hereditary screening is a process that is very complex and very powerful. heritable screening may detect some inherited traits that may by and by on cause a person to capture a distemper that may alter his/her life. Human life, as with any other organism, is b uilt with cells. A military personnel cell consists of forty-six chromosomes, which are paired into twenty- triple different pairs. Each one of these chromosomes carries thousands of genes. Each gene consists of reading that codes for a particular trait. This information is determined by the desoxyribonucleic acid found in that gene. A gene for one trait may have various alleles that will make one person appear a light different than that of a person with a different allele. An example would be of a person with brown hair. They would have a dominant allele for hair color, where as a person with blond hair would have two recessive alleles for hair color. It is possible to have a enlarge d rate of different alleles for all(prenominal) trait, which is why people look so different from on e another (Reilly, Genetics, Law and Social Policy. p. 7). Although each person does have some variation in DNA, all members of the human species carry more or less the same set of DNA (Griffiths, An Introduction to Genetic Analysis. p. 4). Because there is such a huge number of genes it is a very complicat ed process to isolate and identify the information in the DNA fragments. In these fragments it is possible for researchers to isolate and characterize at the molecular level single genes that are responsible for inherited genetic diseases. Genetic ill health can be divided into three major types. The first type is inherited genetic diseases caused by aberrant forms of genes that are passed on from on... ....
