cloning, which is research into therapy that could provide cures for ailments including cancer, liver disease, blood disorders and spinal injuries, among many others. it invovles stem cells which are important to biomedical researchers because they can be used to generate virtually any type of specialized cell in the human body. stem cells are extracted from the egg after it has divided for 5 days. the egg at this stage of development is called a blastocyst , recombinant dna technology, dna cloning, molecular cloning, or gene cloning all refer to the same process the transfer of a dna peice from one organism to a controlled self-replicating genetic organism such as a bacterial plasmid., reproductive cloning is a technology used to generate an animal that has the same nuclear dna as another currently or previously existing animal. , a group of international scientists urged the united nations to allow regulated cloning of cells from human embryos for medical research, and to reject a proposed global ban on all human cloning. , because the stem cell involved in the extraction process destroys the embryo, which raises a variety of ethical concerns, cloning could provide cures for ailments including cancer, liver disease, blood disorders and spinal injuries. , after being published in the journal of science, quickly accentuated the divide between those who believe cloning should be outlawed entirely and those, including most scientists, who support banning it for reproductive purposes but not for medical research, due to the inefficiency of animal cloning (only about 1 or 2 viable offspring for every 100 experiments) and the lack of understanding about reproductive cloning many scientists and physicians strongly believe that it would be unethical to attempt to clone humans., reproductive cloning can be used to develop efficient ways to reliably reproduce animals with special qualities. for example, drug-producing animals or animals that have been genetically altered to serve as models for studying human disease could be mass-produced. , many claim cloning to be an immoral invention ., our newfound genetic knowledge may also enable us to manipulate our own nature�to enhance our muscles, memories, and moods to choose the sex, height, and other genetic traits of our children., the issue is whether or not to make it a crime to do experiments in which a copy of somebody's dna is inserted into a human egg., cloning will remain a hot topic of debate for years to come and with advances in technology rapidly increasing, the tough issues regarding cloning will be much more prevalent in every day life, and when the time comes to make a decsion about cloning it will be beneficial to know what cloning is, what makes it wrong and what makes it right., cloning and genetic redesign would mean unprecedented control by some people over the lives and life prospects of others. , cloning, cloning right, eliminates the natural order of life which many feel should be maintained., imagine if you wake up one morning and strange men in labcoats are surrounding you, eyeing you like you are a frog about to be dissected, which is actually not far from the truth, because you have something they need. before you know what is happening, your kidney is removed from your body, why? because you are a clone and you were created with the sole purpose of supplying your organs. although this isn't quite a reality today, there is a strong possibility a scenario similar to this one could occur very soon. the implications of such a situation has created much debate and strong opinions. , it could create many more illegal research laboratories and it would be impossible to check what's going on, i am happy to announce the successful derivation of human embryonic stem cells from cloned human blastocysts, said dr. woo suk hwang whose team harvested 242 eggs from 16 female donors, added the dna of adult cells and developed 30 cloned embryos. , to better understand the controversy regarding cloning it is necessary to better understand what cloning is, and how it can be used in a way that some feel is wrong, and others feel is right., cloning wrong, of cloning for therapeutic use is one of dr. woo suk hwang's embryo's produced stem cells--the prized blank slates that scientists believe can be coaxed into brain, muscle and other cells so that one day illnesses like parkinson's can be cured and hearts can be patched as easily as bicycle tires, scientists do not know how cloning could impact mental development. while factors such as intellect and mood may not be as important for a cow or a mouse, they are crucial for the development of healthy humans., (1) recombinant dna technology or dna cloning, (2) reproductive cloning, and (3) therapeutic cloning, therapeutic cloning, also called embryo cloning, is the production of human embryos for use in research. the goal of this process is not to create cloned human beings, but rather to harvest stem cells that can be used to study human development and to treat disease., reproductive cloning could be used to repopulate endangered animals or animals that are difficult to breed. in 2001, the first clone of an endangered wild animal was born, a wild ox called a gaur., most scientists agree that cloning is unsafe, likely to produce offspring with serious abnormalities, there is nothing about our species that would make humans any less clonable than sheep, mice, goats, cows, cats, or any other animal. , cloning
