clone Dolly, researchers took a cell from the udder of a six year old Finn Dorset sheep, and kept in a nutritional solution. They then deprived the cell of the nutrients which made the cell's DNA go into a 'sleeping' state. The nucleus of a sheep egg cell from another ewe was then removed, and inserted the sleeping cell into the now nucleus-free egg cell. The two combined cells with were then given an electric shock, and to the scientist surprise, the combined cells acted like a fertilized egg cell and starting to divideand grow, thus starting the development of Dolly. The egg was then implanted into a third ewe and a few months later, Dolly was born. She was genetically an exact copy of the ewe from which the the udder cell was taken.
From my point of view....Dolly the Sheep. Dolly (July 5, 1996 - February 14, 2003), a ewe, was the first mammal to have been successfully cloned from an adult cell. She was cloned at the Roslin Institute in Midlothian, Scotland, and lived there until her death when she was six years old. Her birth was announced on February 22, 1997..........
