Genetic Engineering :: Genetic Engineering Essays

At the Roslin Institute in Edinburgh, Scotland, Dr. Keith Campbell, director of embryology at PPL therapeutics in Roslin, and his colleague Dr. Ian Wilmut worked together on a project to clone a sheep, dame, from adult cells. On February 22, 1997, they fin ally succeeded. Dolly was the only lamb born from 277 fusions of oocytes with udder cells. Wilmut says there were so some(prenominal) failures because it is difficult to ensure that the annul oocytes and the donor cell ar at the same stage of the cell division cycle.To clone Dolly, basically scientists took an unfertilized egg cell, removed the nucleus, replaced it with cells taken from the organism to be cloned, put it into an empty egg cell which begins to develop as an embryo, and implanted this embryo into a mother, from which the clone was born.The fact that only 1 out of 277 attempts succeeded is a minute scary when applied to gracious beings. If an attempt to clone a human led to that high of a death toll, then there would non be many supporters. According to Rifkin, in an extensive survey of all 106 clinical trials of experimental element therapies conducted over the past five old age involving more than 597 patients, a panel of experts convened by the NIG reported that "Clinical dexterity has not been definitively demonstrated at this time in any gene therapy protocol, despite anecdotal claims of successful therapy." (545). These results are also happening with flock who are trying to get gene therapy. With these facts on the table, it would not be ideal to try to clone humans if cloning an animal took some(prenominal) hundred attempts and human gene therapy has had hundreds of failures as well.Humans are going panache beyond their limits in the field of biotechnology in the world today. Until recently, these ideas were unhearable of. Now with new technology, scientists are capable of changing an organisms genetic make-up. We are very eager to learn new things, however, this e agerness gets in the elan of common sense all too often. As stated in Starr and Taggarts article, "we do not have the wisdom to bring about good changes without causing great harm to ourselves or to the environment." (514). However, the nave public may want to jump right into things, and scientists will not disagree.Scientists are messing with things that they should not be messing with.
