Cloning
The possibility of human cloning, raised when Scottish scientists at Roslin Institute created the first successful animal clone of a sheep, "Dolly."Cloning refers to copying genes and other pieces of chromosomes to generate enough identical material for further study. Two other types of cloningproduce complete, genetically identical animals. Blastomere separation (sometimes called "twinning" after the naturally occurring process that creates identical twins) involves splitting a developing embryo soon after fertilization of the egg by a sperm (sexual reproduction) to give rise to two or more embryos. The resulting organisms are identical twins (clones) containing DNA from both the mother and the father. Dolly, on the other hand, is the result of another type of cloning that produces an animal carrying the DNA of only one parent. Using somatic cell nuclear transfer, scientists transferred genetic material from the nucleus of an adult sheep's udder cell to an egg whose nucleus, and thus its genetic material, had been removed. (All cells that are not egg or sperm cells are somatic cells.) One goal of this and similar research is to develop efficient ways to alter animals genetically and reproduce them reliably. Alterations have i
So I think that there just needs to be more research on cloning done. Cloning is seen as a possible way to aid some people who have severe medical problems. Not all cloning would involve creating an entirely new human being. And one can surely imagine clones being created who are not abused in any way. Also if there does happen to be human clones then it would cost too much to get organs from a clone when you must try about 18 times to get a good enough clone. But people can and have treated others as property, we call it "slavery" ,for years, and to date none of the slaves have been clones. Zavos said that there are hundreds of couples already lined to pay approximately $50,000 for the service. One potential use of cloning technology would involve creating a human repair kit. Cloning technology also may someday be usedin humans to produce whole organs from single cells or to raise animals having genetically altered organs suitable for transplanting to humans. There are many pros and cons to the cloning of humans. ncluded adding genes (such as those for human proteins) to create drug-producing animals as well as inactivating genes to study the effects and possibly create animal models of human diseases. When you make a clone you are creating just another living and thinking human. All medical research involves some risk before any real good can come out of it. I agree that it is wrong to kill someone so that you can "harvest" his body parts, whether that person is an adult, a child, or an embryo. To some it seems like "playing God," and interfering with the natural process.
