The Uses and Risks of Cloning
Have you ever wondered what it would be like to have an exact replica of yourself? For many years scientists have been trying to understand and improve the process of cloning. According to the Genetic Science Learning Center at the University of Utah, “Cloning is the creation of an organism that is an exact genetic copy of another. This means that every single bit of DNA is the same between the two!” There are many ways cloning is used that scientists are working on. For example, there is therapeutic cloning, reproductive cloning, animal models of disease, and pharming. However, even though science is progressing there are many risks of cloning.

The first use of cloning is therapeutic cloning. This type of cloning shows the most potential for medical improvement. Therapeutic cloning is used to make an embryonic clone. First, DNA is taken out of the person and inserted into an egg cell, which is the female reproductive cell. Once the cell is fooled into believing it has been fertilized in a body it starts to divide. When the cells grow into an embryo and stem cells are taken out of it and grown in a lab to make replacement organs, such as hearts, livers and skin. They can also be injected into a patient to grow tissues or organs to treat various ailments and diseases such as Alzheimer's, Parkinson's or Rett syndrome. (Bonsor, Kevin)

Reproductive cloning is similar to therapeutic cloning. The procedure is relatively the same in that DNA is taken out, inserted into a cell, the cell divides, and forms an embryo. The difference is that “the resulting embryo is then implanted into the uterus of a surrogate mother, where it can develop until birth.” (Mollard, Richard, Dr.) Reproductive cloning does not make a genetically new person. Instead, it creates a genetic duplicate of the person’s DNA. This procedure can help infertile couples have a child, and it...
