he two. The udder cell Roslin Institute used contained nearly all the DNA genes in the cell's nucleus. Once Roslin Institute had the "perfect cell" they injected it into an unfertilized egg cell from a Scottish Black face ewe (Research Defence Society). The egg cell from the Black face ewe had had its nucleus removed, thus the cell only had the cytoplasm around it before the nucleus of the white face sheep was injected (Research Defence Society). Once injected, Roslin Institute used electrical pulses to fuse the cells of the white face sheep and black face sheep together (Research Defence Society). When the nucleuses were fused they cultured the cell to make sure the cell would develop into an embryo (Research Defence Society). After the cell developed, Roslin Institute implanted the cell into a surrogate mother (Research Defence Society). Five months later Dolly was born and just as health as a normal lamb.
             Four years later Dolly is one the world's most famous sheep. She lives a very pampered life at Roslin Institute (Research Defence Society). She has mated and produced normal offspring in the normal way showing that cloned anima
