The "cloning debate" has now been joined by the "stem cell debate," and it is imperative that people appreciate the difference between Adult DNA Cloning and Therapeutic Cloning. Adult DNA cloning: (also known as somatic cell nuclear transfer) This process begins by removing an egg from a donor mother and extracting the nucleus, this creates an enucleated, essentially empty egg. ... (No matter how a somatic cell is obtained, it contains the DNA of the person, and thus contains all of the information required to produce a duplicate or cloned person) It is then placed in the womb of the mother...

From there, a single skin cell (somatic cell) would be removed from either, or both, parents and the nucleus from these somatic cells would then be inserted into the "empty" egg thus fertilizing an egg for development inside a womb like any other conceived egg, but without the emotionally, financially, and physically draining process of other fertility treatments with a much higher predicted success rate. ... In a lesbian couple, the DNA of one mother would be combined with an egg extracted from the other mother figure, fertilizing it and reinserting it into the womb to carry out the...

After sperm fertilizes an egg, a zygote formes which has the potential to develop into a complete embryo. The fertilized egg is a totipotent stem cell; it has the potential to create any type of cell necessary for embryonic development (this included extraembryonic membranes and tissues, the embryo itself, and all postembryonic tissues and organs). In the first few hours after fertilization, the fertilized egg undergoes several cell divisions that produce identical totipotent cells. ... Stem cells from those stages that match the patients DNA are needed to minimize the danger of rejection. ...

In order to clone, a cell from an adult mammal is used to grow another, genetically identical clone. The nucleus of the removed cell is removed, and transferred into an egg from which the DNA has been removed. ... An alternative method is to immerse eggs in spermatozoa before bokanovskification makes the resulting embryos into hundreds of identical cloned Gammas, Deltas, and Epsilons. ... Cell structures called telomeres gradually shorten as cells divide and age. ... The premature aging of clones may be linked to the fact that the cells taken from animals have already aged, and when cloned e...

In humans, the method would start with a single cell - any cell may do - taken from the adult who wants to be cloned. Using an electrical jolt, scientists would fuse the genes from that cell with a specially treated donor egg cell whose own genes had been removed. That cell would be allowed to grow into an embryo in the laboratory. ... Unlike adult stem cells, embryonic stem cells can develop into any one of more than 200 tissues in the body, from insulin-producing cells that may one day treat diabetes to heart cells that may repair cardiac muscles. ... Maybe the whole cloning issue shouldn&#...
