The controversy over cloning stems from an uninformed public.

Introduction

The controversy over cloning stems from an uninformed public. Cloning does have the potential to be used for bringing back exact genetic copies of deceased peoples and picking genetic traits in unborn children, but these are not practical or ethical applications. The ability to recreate the early stages of the human developmental process allows scientists to access certain cells that are not present in a fully developed human. These totipotent, multipotent, and pluripotent cells have the ability to generate forms of tissues with the same DNA as the donor. The ability to recreate certain cells or tissues opens to doors to many life saving and disease curing techniques. If human cloning is made legal for select purposes it could help cure diseases like diabetes, leukemia, kidney failure, and revolutionize the world of medicine. A Short History On Cloning There are two ways in which an embryo can be cloned. The first process is called fission. This is when a fertilized egg (an embryo) splits into two in the first stage of cell development, creating two masses that will mature into genetically equivalent offspring (Savulescu 1). In this instance two haploid cells, one from each parent, merge to create a unique genetic makeup. ...read more.

These cells can be used to treat diseases such as leukemia or diabetes. This works by inserting a concentration of these multipotent cells in a diseased area. Take leukemia for example. This disease is caused by defective bone marrow creating abnormal amounts of white blood cells. If healthy multipotent bone marrow cells are then introduced into this area there is the potential for healthy bone morrow to develop, curing the disease (Wilson, 5). Where does human cloning come in? Cloning is involved in the process that creates these cells. Much like the organ-donning scenario, the recipient must not reject these stem cells. This could theoretically be accomplished by creating an embryo from recipient DNA. These multipotent cells could then be removed from the embryo in the early stages of cell differentiation and placed into the recipient, eliminating all rejection reactions. Cloning techniques could also be combined with many other research techniques and medical procedures to make them more effective. One example of this is germ line gene therapy. This new medical technique involves correcting negative recessive traits in early embryonic development. Essentially what takes places is the diseased gene is removed and replaced with a healthy one. ...read more.

Conclusion

Others argue that human cloning technology will have a negative effect on the gene pool. An anonymous article in the Catholic Medical Journal declares, "It destroys the dignity of human nature by treating the human person as a material commodity to be manipulated by whim and fancy" (1). This animosity extends even to procedures which could cure genetic birth defects. This is quite contradictory however. These genetic diseases are treated for people's entire lives. These people pay doctors to help them feel better. They buy pharmaceuticals to relieve pain. It is obviously realized by humans as a whole that these diseases are bad. Furthermore, humans then strive to cure the person and if not cure them make them as close to an unaffected human as possible. Why not then just remove the defect at conception. It seems the largest opposition to human cloning involves the manipulation of traits on a large scale. Tissue transplants, organ culturing, and germ dine therapy are just used to correct obvious faults before birth. These defects, if not corrected at conception, would attempt to be cured after birth. These procedures would not involve the maturation of babies to a conscience level or the creation of an "imitation" human. If human cloning is regulated it can be combined with many other types of research to proliferate healthy, genetically diverse, human life. ...read more.
