Embryonic Stem Cells Adult Stem Cells
894 wordsStem cells look to be nothing more than a hollow sphere composed of a clump of tiny, roundish balls. In reality, they are much more than that. Those 40 cells contain all the potential to become a living, breathing human being. Many scientists believe that these cells also have the potential to cure a myriad of diseases, including Alzheimer's disease, Parkinson's disease, diabetes, and many others. The cells of the four day old human embryo can be programmed to become virtually any cell in the bo...

Type Of Cloning Desirable Traits
1,048 wordsGenetic engineering is the changing of an organism's DNA, genetic material to eliminate unwanted traits or to produce desirable traits. The earliest form of genetic engineering dates back to the scientist Gregor Mendel who did experiments with peas. He bred only the peas with the most desirable traits in order to achieve a healthier and stronger pea (McCuen 8). This method, called selective breeding, is still used today with plants and animals in order to increase food production. Corn plants ar...

Embryonic Stem Cells Stem Cell Research
1,813 wordsThe Stem Cell Dilemma Every day, nearly 3, 000 people die while waiting for an organ transplant (D'Agnese). Moreover, 66, 000 people are still on an organ donor list in the United States, few of which will ever see their name come up on that list ("Improving"). Many people believe nothing can be done about this sad fact. However, this is not the case. Studies on stem-cell research point toward a solution to this deadly problem. With efficient use of stem cells, many diseases and medical problems...

Human Embryo Cloning Vitro Fertilization
1,759 wordsWhat if Cloning Cloning Benefits What if while walking down the street you encountered someone who looked exactly like you? Would you stare in amazement or would your heart be filled with fear? At first some people may look upon the idea of cloning with disgust and question themselves if humans should play God while others would be interested and study the many possibilities that cloning offers. This illustrates the path that cloning has taken over the latter part of the twentieth century. At fi...

Clone A Human Zona Pellucid
2,092 wordsThe idea that humans might someday be cloned has started sounding less like a science fiction novel and more like a genuine scientific possibility. On February 23, 1997, The Observer broke the news that Ian Wilmut, a Scottish scientist, and his college at the Roslin Institute were about to announce the successful cloning of a sheep by a new technique which had never been successfully used before in mammals. This technique involved transplanting the genetic material of an adult sheep, obtained fr...

Mary Shelleys Frankenstein Cloning Of Humans
1,951 wordsThe process of cloning is the process of using the genes of a being to create another being genetically identical to it. Cloning technology has been called the forbidden fruit of biology (Begley 54). For years, scientists have been trying to perfect the cloning technique. In Scotland, scientists at the Roslin Institute have finally succeeded. Their success comes in the form of a Finn Dorset ewe named Dolly. Dolly is a clone. Now that the cloning of mammals from body cells has been accomplished, ...
