The Cloning Debate :: Cloning Argumentative Persuasive Argument
The copy Debate The first attempt in cloning was conducted in 1952 on a group of frogs.The experiment was a partial success. The frog cells were cl whizzd into other(a)living frogs however, only one in every thousand positive normally , all ofwhich were sterile. The rest of the frogs that survived grew to vicariously largesizes. In 1993, scientist and manager of the in vitro lab at GeorgeWashington University, Jerry Hall and associate Robert Stillman, account thefirst ever successful cloning of human conceptuss. It was the discovery of in-vitro fertilisation in the 1940s that began the pursuit to ease the sufferingof infertile couples. subsequently years of research, scientists learned that in atypical in-vitro procedure, doctors will throw in three to five embryos in hopesthat, at most, one or both will implant (Elmer-Dewitt 38). And that a womanwith only one embryo has about a 10% to 20% chance of getting significant throughin-vitro fertilization. If that embryo could b e cloned and turned into three orfour, thechances of a successful pregnancy would increase significantly(Elmer-Dewitt 38). The experiment the scientists performed is the equivalent of a motherproducing twins. The process has been practiced and almost perfected in ancestry for the past ten years, and some scientists recollect that it seems onlylogical that it would be the next step in in-vitro fertilization. The procedurewas remarkably simple. Hall and Stillman selected embryos that were abnormalbecause they came from eggs that had been fertilized by more than one sperm(Elmer-Dewitt 38), because the embryos were defective, it would have been insufferable for the scientist to actually clone another person. They did however,split the embryos into separate cells, as a result creating separate andidentical clones. They began experimenting on seventeen of the defectiveembryos and when one of those single-celled embryos divided into two cellthescientists quickly separated the cells, crea ting two different embryos with thesame genetic information (Elmer-Dewitt 38). The cells are coated with aprotective covering called a zona pellucida, that is essential to development(Elmer-Dewitt 38), which was scanty away and replaced with a gel-likesubstance made from seaweed that Hall had been experimenting with. Thescientists were able to ca-ca forty-eight clones, all of which died within sixdays. Other scientist have been quoted truism that although the experiment isfairly uncomplicated, it had not been tested before because of the moral and honest issues surrounding an experiment such as this one. Some people believethat aiding infertile couples is the only true benefit to cloning human embryos,
