What the researchers actually did: they took an unfertilized egg cell from a female sheep and removed the entire DNA (genetic information) from the nucleus that is needed to produce an embryo. ... But this was the first time anybody had made adult mammal genes behave like genes in a fertilized egg. ... The technique would involve taking an unfertilized egg from a human female, removing the nucleus that contains the genetic information, and replacing it with the nucleus from a cell " any cell " of the person to be cloned.

Frogs were successfully cloned as early as 1953(Dixon, P., 2000) and identical twins have been made in the lab by mechanically splitting a fertilized egg, although these eggs were never allowed to grow and develop. ... There is the forced splitting of a fertilized egg as mentioned above, and the more talked about and controversial method of nuclear transfer. ... Stem cell cloning is the growing of specific cells in the lab such as liver or spinal ti...
