Dolly the sheep

Dolly (5 July 1996 – 14 February 2003), a ewe, was the first mammal to have been successfully cloned from an adult cell. She was cloned at the Roslin Institute in Scotland and lived there until her death at the age of six. Scientists announced her birth on 22 February 1997.

The name "Dolly" came from a suggestion by the stockmen who helped in the process, in honour of Dolly Parton, because the cloned cell was a mammary cell http://news.bbc.co.uk/hi/english/sci/tech/newsid_769000/769915.stm. The particular technique that was made famous by her birth is somatic cell nuclear transfer, in which the nucleus from one of the donor's non-reproductive cells is placed into a de-nucleated embryonic cell (which is then coaxed into developing into a f?tus). When Dolly was cloned in 1996 from a cell taken from a six-year-old ewe, she became the centre of a controversy that still continues today.
