To Ban or Not To Ban?
             Cloning is a fascinating and very new technological break-through us humans have discovered. The first mammal to be successfully cloned was the sheep "Dolly." This sheep signified the beginning of many new medical discoveries about how DNA (Deoxyribonucleic acid) works. Many people believe that the use of cloning technology is unethical and should be banned. I think that cloning technologies should be embraced and furthered. The benefits that cloning could give humans far outweigh the detrimental aspects. There are medical benefits to be had as well as the power to reverse some of the harmful things humans have done to the planet.
             In February 1997 Ian Wilmut and his colleagues at the Roslin Institute in Scotland announced a stunning news that they had cloned a lamb from the cells of a mature sheep. Although many animal cloning experiments have been performed in the past, they have succeeded only in cloning the cells of embryos. This latest experiment has been remarkable because it was the first successful attempt to clone a mature mammal, producing an exact physical replica of the adult animal.
             In what is considered a normal reproduction of mammals is when a sperm and an egg fuse naturally, each one contributing half of the material that makes up a genetically unique individual. However, the process that was used to create "Dolly" is quite different. This process is known as gene transfer in which a cell is mechanically fused from one animal onto an egg cell whose nucleus has been removed (enucleated egg cell). Since the egg cells do not have deoxyribonucleic acid (DNA), the embryo created contain the DNA from only one source. As a result the embryo will develop into an exact physical replica of the animal from which the cell containing the DNA was taken.
             Scientists had thought that gene transfer could only be performed using embryonic cells, in which all the genes are act...
