Cloning

 

             The definition of the word cloning is; an organism that is genetically identical to the individual from which it was asexually derived from. This term has been heard for so many years around the world and has been going on for a while now. The first type of cloning started with plants then animals and now Humans.
             Three different procedures have been referred to as "cloning". Two of them are: Adult DNA cloning and Therapeutic cloning. "Adult DNA cloning involves removing the DNA fro an embryo and replacing it with the DNA from a cell removed from an individual. Then the embryo would be implanted in a woman's womb and be allowed to develop in to a new human whose DNA is identical to that of the original individual. This method has been used to clone a sheep. The initial steps of the procedure were tried using human DNA in December 1998. Adult cloning cannot ethical be used to produce a human clone, because experiments on animals have sometimes produced defective specimens." The other type of cloning, "Therapeutic cloning starts with the same procedure as is used in adult DNA cloning. The resultant embryo would be allowed to grow for perhaps fourteen days. Its stem cells would then be extracted and encouraged to grow into a piece of human tissue or a complete human organ for transplant. The end result would not be a human being; it would be a replacement organ, or piece of nerve tissue, or quantity of skin." .
             In the year 1996, sometime in the month of May, news broke out that had shocked the nation. A sheep named Dolly was the first ever mammal to be created from a single cell of an adult through cloning. The creator of Dolly is a Scottish scientist by the name of Dr. Walnut, who helped raise the question " are human next?" The answer was that it is possible, but the question should be that " Should Humans Be Cloned?".
             There are many advantages as well as disadvantages to humans cloning, but before we get into the issue about cloning we need to explore the advantages of cloning, which is not bad itself.
