... it stops growing. Scientists need to determine whether ES cells can be taken from an embryo, which was created by fusing a human egg with a stripped cow egg. Cibelli refuses to talk about what they have done and their progress surrounding their project, but they have gone to a European patent ... the process. (Daniel Pendick, August 16, 1997) A study presented at a meeting of the International Embryo Transfer Society in Boston suggests that cow egg cells and cloning may also come to the rescue of many endangered animals. Cloning could possibly be the technology that preserves these end...

... life and it's regeneration and brings it to life through the process of cloning. In 1938 a German scientist Hans Spemann proposes a "fantastical experiment" to transfer one cell's nucleus into an egg without a nucleus, the basic method that would eventually be used in cloning. Fourteen years later in 1952 Briggs and King clone tadpoles. Another scientist John Gurdon clones frogs from differentiated ... a fatal disease could wipe out the human race. In order to have a better understanding of cloning it is important to understand that cloning has three different divisions: embryo cloning, ...

Simply explained, the nuclear transplantation process involves taking a donor egg cell and removing the nucleus (removing all DNA). Then a mammary cell, one which has all the DNA needed to make another being, is taken from the subject that is too be cloned. Then the cell is fused with the ... egg cell with a jolt of electric current. The cells begin to multiply into generic stems cells (cells that are not specified and can become any ... ...
