              NUCLEAR TRANSFER: DOLLY THE SHEEP.

Nuclear transfer is a form of cloning. The steps involve removing the DNA from an oocyte (unfertilized egg), and injecting the nucleus which contains the DNA to be cloned. In rare instances, the newly constructed cell will divide normally, replicating the new DNA while remaining in a pluripotent state. If the cloned cells are placed in the uterus of a female maman, a cloned organism develops to term in rare instances. This is how Dolly the Sheep and many other species were cloned. Cows are commonly cloned to select those that have the best milk production.
Dolly the Sheep was cloned at the Roslin Institute in Midlothian, Scotland, and lived there until her death when she was six years old. The name "Dolly" came from a suggestion by the stockmen who helped with her birth, in honor of Dolly Parton, because it was a mammary cell that was cloned. When Dolly was cloned in 1996 from a cell taken from a six-year-old ewe, she became the center of much controversy that still exists today. After cloning was successfully demonstrated through the production of Dolly, many other large mammals have been cloned, including horses and bulls.
