Dolly+the+Sheep

**Dolly the Sheep** Febuary 14, 2003 Dolly the Sheep was cloned by a ewe, which is a female adult sheep, successfully. She had a normal life by living to 6 years old. The technique that was made famous by her birth is somatic cell nuclear transfer, in which a cell is placed in a de-nucleated ovum, the two cells fuse and then develop into an embryo. She was named after Dolly Parton. Dolly was the first clone produced from a cell taken from an adult mammal. Dolly’s birth is still recognized as one of the major achievements in the development of modern biology. She was bred and had six lambs. On February 14 2003, Dolly past away because of a progressive lung disease and severe arthritis. This sheep has led to many other cloning to bulls and horses. Kristen Briggs March 13, 2010
