Cloning :: essays research papers

Human embryo cloning should not be done because of the religious, moral, ethical, and social concerns that it places upon the human race. Although there may be some positive affects to cloning humans, there are far too many opposing factors in this situation. Many religious leaders of expressed their concern and condemnation of human cloning. The moral and ethical aspects outweigh any scientific evidence, and the social concerns are frightening. The most important question that needs to be asked, is whether the gains out weigh the losses--the gains being scientific research and the losses being the religious, moral, ethical, and social concerns that it poses on today’s society. A clone, as defined in â€Å"The Human Genome Project,† is; 1. a population of genetically identical unicellular organisms or viruses arising from successive replications of a single ancestral unicellular organism or virus. 2. a recombinant clone. 3. the fragment of foreign DNA contained in each member of a recombinant clone. 4. a population of identical cells arising from the culture of a single cell of a certain type, such as a human fibroblast or a rodent-human hybrid cell containing a full set of rodent chromosomes and a single human chromosome. Human embryo cloning starts with a standard in vitro fertilization procedure. Sperm and an egg cell are mixed together on a glass dish. After conception, the zygote (fertilized egg) is allowed to develop into a blastula (a hollow mass of cells). The zygote divides first into two cells, then four, then eight... A chemical is added to the dish to remove the â€Å"zona pellucida† covering; this material provides nutrients to the cells to promote cell division. With the covering removed, the blastula is divided into individual cells which are deposited on individual dishes. They are then coated with an artificial zona pellucida and allowed to divide and develop. That is how a human embryo clone is made using the â€Å"twinni ng method.† Some scientists believe that human embryo cloning and related research can have some positive results, however, many religious leaders feel that cloning and related research should not be permitted. Religion and science have been involved in an ongoing battle over many subjects in the past, but human embryo cloning has caused the biggest debate thus far. Many religious philosophies teach that human life is unique and special and should be created, determined and controlled only by their deities.
