Genetic Engineering: The Controversy of Genetic Screening Essay

The Controversy of Genetic back Craig Ventor of Celera Genomics, Rockville, MD, and Francis Collins of the National Institutes of Health and Wellcome Trust, London, England, simultaneously presented the sequence of human desoxyribonucleic acid in June of 2000, accomplishing the first major endeavor of the Human Genome Project (HGP) (Ridley 2). As scientists link human characteristics to genes-segments of DNA piece on one or more of the 23 human chromosomes-prospects for contagious engineering will sum up dramatically. One relatively simple but powerful application of the HGP is genetic screening. By abstracting and analyzing DNA from embryos, fetuses, children or adults, one can detect the bearing or absence of specific genes. While some people cerebrate of genetic screening as a great scientific and checkup advancement, others see it as a frightening and dangerous enterprise. With careful regulation, I believe genetic screening can affect individuals in a beneficial manner. Pre-natal genetic screening is currently used in high-risk pregnancies for detection of diseases such(prenominal) as Down Syndrome and Huntingtons chorea (Ridley 55, 98). As scientists attend the genes for additional genetic conditions, screening of embryos will provide more study to potential parents before their fetus is fully developed. If a screened fetus were found to carry genes for a particular disease or disability, its parents might selectively abort it. Many individuals who believe in pro-choice abortion laws prophesy pre-natal screening for genetic diseases because the abortion of fetuses with undesirable traits may decrease the deem of unwanted children. Those against abortion strongly oppose pre-natal screening, predicting an increase in abor... ...guidelines could blow over many of these destructive effects. Pre-natal screening should only test for abortion-worthy diseases determined by a national or international bioethics committee. Children and adults shoul d be screened for particular diseases or conditions when/if family medical histories or physical examinations find reason to do so. With such policies, I believe that genetic screening will beneficially animate obstetric and preventative medicine. Works Cited Gibbs, Nancy and Michael Duffy. We Must Proceed With Great Care. Time.
