Dolly was part of a series of experiments at The Roslin Institute that were trying to develop a better method for producing genetically modified livestock. Although the clone died shortly after birth, it was the first time an extinct species was cloned. This was highly significant because it showed that DNA from an adult cell, which has been programmed to express only a distinct subset of its genes, can be used to develop an entirely new organism. The funding for Dolly’s cloning was provided by PPL Therapeutics and the Ministry of Agriculture. With improvement in techniques, cloning of animals has become cheaper and more reliable.

Dolly was important because she was the first mammal to be cloned from an adult cell. The first cloning of an animal was done in the 1880s by German biologist Hans Driesch who cloned a sea urchin from an embryo cell. Dolly meets the world’s media. It is prevalent in nature with organisms such as bacteria, insects or plants reproducing asexually to produce clones. Scientists at Roslin also wanted to learn more about how cells change during development and whether a specialised cell, such as a skin or brain cell, could be used to make a whole new animal. Dolly was located at the Roslin Institute in Scotland. Roslin researchers however stated that other sheep in the same flock had died from the same lung disease. Their first lamb, Bonnie, was born in April 1998, twins Sally and Rosie were born the following year and triplets Lucy, Darcy and Cotton the year after. Cloning FAQs. Dolly captured the public’s imagination – no small feat for a sheep – and sparked a public debate about the possible benefits and dangers of cloning. What made Dolly so special was that she had been made from an adult cell, which no-one at the time thought was possible. It’s thought that Dolly had shorter telomeres were because her DNA came from an adult sheep and the telomeres had not been fully renewed during her development. 10 Interesting Facts About Dolly The Cloned Sheep, #1 She was not the first mammal to be cloned, Cloning is a process by which a genetically identical individual organism is produced. Interesting Cloning Facts: Cloning may make it possible to save endangered species from becoming extinct. They were planted into 13 surrogate mothers.

A Finn Dorset has a life expectancy of around 11 to 12 years but Dolly lived for only 6.5 years. However, extensive health screens on Dolly at the time did not find any conditions which could be directly related to premature or accelerated ageing.

Because 99.9% of the cell’s DNA is contained in the nucleus as chromosomal DNA (with the remaining 0.1% of DNA found in mitochondria), the resulting animal will share almost exactly the same DNA as the original donor cell.
