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 Lee Harvey Oswald for sale on the black market? Is there a way we can possibly outlaw and enforce cloning? Could this development actually be used for a benefit, such as bringing back endangered or extinct animals? The instantaneous reaction of the world has been mixed. However, the overall benefits appear to out weigh the other factors. This new technological development can not be passed off. It has the potential of enormous benefits to society. The new technology of cloning should be utilized because it could bring back extinct organisms, help infertile couples to have children, and potentially save many lives.

Cloning could bring back extinct animals (Kaku 227). Over millions of years, thousands of different species have gone extinct. Most were due to natural selection, while several others were due to human intervention. Approximately two-thirds of all the native bird species (Kendall n/a) and one-fifth of the native plants (Kendall n/a) originally found on the Hawaiian Islands have gone extinct recently. Predators, competitors, or diseases introduced by humans from continental areas are responsible for many of the extinctions. Also, many remaining species on other oceanic islands are threatened or endangered. A benefit of cloning would be the cloning of “endangered species that have difficulty reproducing in captivity” (Kaku 227). Many of the animal species, and numerous plant species could be brought back to life with cloning. Even

though there is currently no technique for bringing the plants back, with technology advancing so quickly, we could have a solution in the near future. Ultimately, cloning could have significant human applications.

Cloning could help a couple unable to have children because one of them was infertile. In the case of an infertile father, scientists take an egg from the mother, remove its nucleus, then take a cell from the father, remove its nucleus, and place the nucleus inside the empty egg (Kolate 242). That cell acts as a reproductive cell. They then put the egg in the mothers' womb to impregnate her. “Mark Sayer, an infertility expert at Columbia Presbyterian Medial Center in New York, would like to take each cell from an early human embryo and clone it, making identical twin embryos in the woman’s uterus immediately, and freeze any extras for future attempts at pregnancy” (Kolate 242). The attempt would prove that the process of reprogramming a cell’s DNA begins with clones...
