In 1996, Scottish scientist Ian Wilmot and his research team was able to successfully clone a lamb named Dolly from an adult sheep. This invention shocked all of the world at the realization that cloning was no longer a fantasy or an element of a Science Fiction movie. Since then, human cloning has become one of the most debated topics in the world. Everyone started to discuss about its advantages or the ethical issues of human cloning. Most of the people were against it and called it an ‘evil’ experiment. In several recent polls by Cable News Network (CNN) and TIME magazine (The Ethics of Cloning, 1998), it was shown that seventy five percent of the responding population thought that ...view middle of the document...

This technique is called “Nuclear Transfer” or “Nuclear Substitution.” It is the process in which the DNA of a female egg cell is replaced with different DNA from another cell. The nucleus of the unfertilized female egg cell containing the DNA is removed and is replaced with the nucleus of another cell. Then the cell is manipulated and genetically engineered to believe that it has been fertilized and is implanted into the womb of the mother. The cell divides and re-divides inside the mother to develop into an embryo, which develops into a fetus and a baby is born in nine months, just like any other baby. The only difference between the cloned baby and a normal baby is that the cloned baby shares the same exact DNA with another person, just like identical twins share the same DNA, only that the clone is much younger than its twin. The baby will grow up to be identically similar to its adult twin. Therefore, some peoples’ beliefs that human cloning is a very complicated and an ‘evil’ process are baseless as it involves the natural process of childbirth with a little touch of genetic engineering.

One of the biggest reasons for keeping cloning legal is that this technology can help the infertile couples. There are many couples in the world who are unable to have babies due to certain issues in either of the parents. In such cases, one or both of the individuals is unable to naturally give their genes for the purpose of procreation. Also, according to a recent survey, “…about fifteen percent of Americans are infertile, and doctors often cannot help them” (Eibert, 1998). However, through cloning we can help these people by allowing them to give birth to a child that is genetically related to them. In this process, the sperm of an infertile man is cloned and the undamaged sperm is used for fertilization. Similarly, an infertile woman can have an egg cloned and the fertile egg can be used for conception. The infant would have the same set of genes as one of the parents and would be identical to one of them. In this way, the parents will have the satisfaction that the child is their own and that their genes will be passed on to the future generations. Thus, human cloning will prove itself very useful as a tool for infertility.

It is also possible through cloning to grow “spare parts” of the human body to be used in organ transplants. Once the cell has been cloned and it starts dividing, it is not necessary that it will grow into an entire new individual. Researches have proved that through a series of tasks, it is possible to hold the cell from dividing into a complete new person and change its nature to develop into specialized cells or even complete organs. For example, a heart or a kidney could be grown outside of the body to be used in organ transplants without the fear of rejection from the recipient’s body, eliminating the need for anti-rejection drugs. In the same way, skin cells can be cloned in laboratories for skin transplants for the burn...
