Cloning
Dolly, a Finn-Dorset ewe, was the first mammal to have been successfully cloned from an adult somatic cell. Dolly was formed by taking a cell from the udder of her 6-year old biological mother. Dolly's embryo was created by taking the cell and inserting it into a sheep ovum. It took 434 attempts before an embryo was successful. The embryo was then placed inside a female sheep that went through a normal pregnancy. She was cloned at the Roslin Institute in Scotland by British scientists Sir Ian Wilmut and Keith Campbell and lived there from her birth in 1996 until her death in 2003 when she was six. She was born on 5 July 1996 but not announced to the world until 22 February 1997. Her stuffed remains were placed at Edinburgh's Royal Museum, part of the National Museums of Scotland.
University of Edinburgh
The Roslin Institute is an animal sciences research institute which is sponsored by the Biotechnology and Biological Sciences Research Council. The Institute won international fame in 1996, when Ian Wilmut, Keith Campbell and their colleagues created Dolly the sheep, the first mammal to be cloned from an adult cell, there. A year later Polly and Molly were cloned; both sheep contained a human gene.
