Although as far as we know, human cloning has not yet been attempted; there are several different reasons why society might want to use this new science. First a quick definition of the three types of cloning; embryo cloning, adult DNA cloning and therapeutic cloning. Then a whole list of possible reasons that people might embrace this new advancement and some of the downsides to these reasons.
First off, we have embryo cloning, which is a technique that produces twins or triplets. This procedure involves the removal of one or more cells from a fertilized embryo, which are then encouraged to develop into one or more duplicate embryos. The end result of the procedure will have identical DNA (http://www.religioustolerance.org). This procedure has been done on various other species, but never on humans as far as we know. People who would like to have a large family or who have trouble conceiving children might want to use this technique. .
Adult DNA Cloning.
Adult DNA Cloning, which is also known as cell nuclear replacement, somatic cell nuclear transfer or reproductive cloning is used to produce a duplicate of an existing animal, for example Dolly the sheep. In this process, the DNA is removed from an ovum and replaced with the DNA from a cell removed from an adult animal. Then the fertilized ovum, called a pre-embryo is implanted in a womb and allowed to develop into a new animal (http://www.religioustolerance.org). This procedure has never been done on humans as far as what has been documented.
Therapeutic cloning starts out the same as Adult DNA cloning; the difference is the fact that the stem cells are removed from the pre-embryo with the result of producing a whole organ or tissue for transplant back into the DNA donor (http://www.religioustolerance.org).
Why Do We Want To Clone Humans? (The Reasons).
There are several reasons why humans might want to make cloning a part of their everyday lives, and some of the reasons are selfish.
