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..........
