What is the story of Dolly the sheep?
Dolly the sheep was successfully cloned in 1996 by fusing the nucleus from a mammary-gland cell of a Finn Dorset ewe into an enucleated egg cell taken from a Scottish Blackface ewe. Carried to term in the womb of another Scottish Blackface ewe, Dolly was a genetic copy of the Finn Dorset ewe.
Why Dolly the sheep is important?
Why was Dolly so important? Dolly was important because she was the first mammal to be cloned from an adult cell. Her birth proved that specialised cells could be used to create an exact copy of the animal they came from.
How long did Dolly live?
6.5 years
A Finn Dorset such as Dolly has a life expectancy of around 11 to 12 years, but Dolly lived 6.5 years. A post-mortem examination showed she had a form of lung cancer called ovine pulmonary adenocarcinoma, also known as Jaagsiekte, which is a fairly common disease of sheep and is caused by the retrovirus JSRV.
What did Dolly the sheep teach scientists?
Dolly the sheep proved that it was possible to take a cell from a specific adult animal, and then use that cell to make a genetic copy of that adult animal.
How did Dolly change the world?
TWENTY years ago Dolly the sheep, the first animal clone, was revealed to the world. She caused a sensation. Many scientists had believed cloning animals was impossible. Dolly’s creation showed that DNA in a differentiated cell could be repurposed through nuclear transfer, opening up two new possibilities.
What did we learn from Dolly the sheep?
Her birth proved that specialised cells could be used to create an exact copy of the animal they came from. This knowledge changed what scientists thought was possible and opened up a lot of possibilities in biology and medicine, including the development of personalised stem cells, known as iPS cells.

What kind of sheep was Dolly?
Finn Dorset sheep
Dolly was cloned from a cell taken from the mammary gland of a six-year-old Finn Dorset sheep and an egg cell taken from a Scottish Blackface sheep. She was born to her Scottish Blackface surrogate mother on 5 July 1996.
What does Dolly have on her hands?
However, I can relay third-hand information that she was asked about the gloves by fans while filming scenes for her upcoming movie Joyful Noise and told them that last year she had had corrective hand surgery (medical, not cosmetic) and it left a scar that she’s covering.
Did Dolly ever marry?
Country music legend Dolly Parton has been married to Carl Dean for more than 55 years — though the public has hardly seen him at all in that time. But Tuesday afternoon, she shared a fun throwback photo of the two of them together to promote her latest line of merchandise.
