CLONING FROM AN ADULT CELL
Dolly the sheep is the face of cloning. She made headlines as the first clone to come from an adult cell. Prior to her birth in 1996 at the Roslin Institute in Edinburgh, all other successful cloning was done using embryonic cells. This experiment proved that adult DNA can be used to create another organism with identical genetic material.
At the age of 6, Dolly was euthanized after battling a lung infection. She was able to produce multiple offspring during her lifetime, all by natural birth. Dolly was taxidermied and is now on display at the National Museum of Scotland. (The New York Times)
