Unlike some movies, real-life cloning does not produce an exact replica of someone. One type of cloning that occurs naturally is when identical twins are born (“What is cloning?”). Somatic cell nuclear transfer (SCNT) is a type of cloning that must be performed in a laboratory. In SCNT they take the nucleolus from an egg cell, replace it with the nucleolus from a somatic cell (body cell with two complete sets of chromosomes), and cause the egg cell to divide into a blastocyst (“What is cloning?”). There are two main controversial types of cloning resulting from SCNT: reproductive and therapeutic cloning. Reproductive cloning involves the creation of another life and should be banned. “In therapeutic cloning… there [is] no implantation in the uterus to create a child” (Murnaghan). It is used to create stem cells for medical use and can save lives. The medical possibilities of stem cells are immense and should be pursued with caution. People who want to pursue reproductive cloning do so primarily for infertility reasons. For some people who have difficulty conceiving a child and desperately want one, reproductive cloning would be a godsend. “If doctors could create many identical copies of an embryo, they could avoid having to give women powerful drugs, month after month, to force their ovaries to produce more eggs” (Kolata). This would save time and money. Cloning would also provide an option for those who want a child who is genetically related to them but who is completely sterile. Even with the possibility that reproductive cloning could help solve infertility issues, it is extremely dangerous and unethical. Previous experiences with reproductive cloning in animals have produced terrible results. “F...... middle of paper...... 2014. .The cloning process. Digital image. Gurukpo.
