Clonong
Cloning Twenty-five years ago, scientists thought that cloning was virtually impossible. In the last five years, the science of cloning, has come to realization. What is a clone? A clone is a duplicate - much like a photocopy is a duplicate, or copy, of a document (Kolate, 238). A good example of copies that occur in nature are identical twins, which are duplicates of each other. On a daily basis, molecular geneticists and other scientists use cloning techniques to replicate various genetic materials such as gene segments and cells (Kolate, 238). Recently the cloning of a living life form was brought from the realms of science fiction to reality with the cloning of a sheep named Dolly (Kolate 236). Imagine meeting an exact replica of somebody or yourself seven to ten years from now (Kaku 6). They look alike, and even have the same genetic makeup. This is the new world of cloning. As with every new science, there are those who believe in it, and those who oppose it. So many questions arise. What if some one like Hitler had access to this technology? Would people want two identical copies of a child or a relative? What are the chances of people illegally obtaining blood samples of, for example, Albert Einstein, Bill Clinton, or even
Ultimately, cloning could have significant human applications. Over millions of years, thousands of different species have gone extinct. Medical scientists would be able to not only reproduce the genes, but would be able to transfer them and to study them (Kolate 236). This new technological development can not be passed off. Most were due to natural selection, while several others were due to human intervention. Because of the overwhelming positive implications, society must embrace this the idea of cloning. Cloning could bring back extinct animals (Kaku 227). However, the overall benefits appear to out weigh the other factors. That cell acts as a reproductive cell. "A major goal of scientists working on cloning is to clone genes that direct the production of medically significant uses in treating disease" (Robel n/a). With recent advances moving along at such speed, cloning will become an integral part of our society. The idea that future clones could produce such medically important substances as Insulin, interferon, and growth hormone is exciting to scientist (Robel n/a). A benefit of cloning would be the cloning of "endangered species that have difficulty reproducing in captivity" (Kaku 227).
