Cloning is based on nuclear transfer. Nuclear transfer involves the use of two cells. The recipient cell is normally an unfertilized egg taken from an animal soon after ovulation. These eggs are poised to suction on the end of a fine pipette and uses an extremely fine micropipette to suck out the chromosomes, sausage- shaped bodies- that incorporate the cell’s DNA. Then, the donor cell, complete with it’s nucleus, is combine with the recipient egg.
What has been cloned? Now, that’s the question that you’re probably asking your self. The three species that have been cloned are mice, calves, and sheep. Recently, Ryuzo Yanagimachi at the University of Hawaii at Honolulu cloned a pair of mice by transferring donor nuclei- not whole eggs- into eggs. Then, he took the nuclei from cells called cumulus cells, which surround the ovary. Second, was Dolly,
