Dolly was a female Finn-Dorset sheep remarkable in that she was the first mammal to
be cloned from an adult cell using the process of nuclear transfer.
She was cloned by Ian Wilmut, Kieth Campbell and colleagues at the Roslin institute near Edinburgh.
She was born on 5 July 1996 and she lived until the age of six. She has been called the world’s most famous sheep
The cell used as the donor for the cloning of Dolly was taken from a mammary gland, that’s a tit to you & me, which is why she was named Dolly after Dolly Parton ! Who said scientist have no sense of humour ?
Dolly lived for her entire life at the Roslin Institute. In the autumn of 2001, at the age of five, Dolly developed arthritis and began to walk stiffly. On 14th of February 2003 Dolly was euthanised, which is a scientific way of saying killed, because she had a progressive lung disease and severe arthritis.
A Finn-Dorset such as Dolly has a life expectancy of around 11 to 12 years, but Dolly lived to be only six years of age. A post-mortem examination showed she had lung cancer. Roslin scientists stated that they did not think there was a connection with Dolly’s being a clone. Yeah right ! Such lung diseases are a particular danger for sheep kept indoors, and Dolly had to sleep inside for security reasons. Not the fault of cloning then ?
It has been suggested that cloning may become a viable tool for reviving extinct spicies & it has also renewed interest in the possibility that in the future it will be possible to reproduce long-dead species such as wooly mamoths and even dinosaurs !
Have they not seen Jurassic Park ?
