  1. Dolly the Sheep By Jim, Matti, Carter, and Charlie

  2. How was Dolly Cloned? • Animal cloning from an adult cell is obviously much more complex and difficult than growing a plant from a cutting. So when scientists working at the Roslin Institute in Scotland produced Dolly, the only lamb born from 277 attempts, it was a major news story around the world.

  3. What happened to Dolly? • Dolly, lived a pampered existence at the Roslin Institute. She mated and produced normal offspring in the normal way, showing that such cloned animals can reproduce. Born on 5 July 1996, she was euthanased on 14 February 2003, aged six and a half.

  4. Not an Average Sheep… • Sheep can live to age 11 or 12, but Dolly suffered from arthritis in a hind leg joint and from sheep pulmonary adenomatosis, a virus-induced lung tumour to which sheep raised indoors are prone.

  5. The End of Dolly • On 2 February 2003, Australia's first cloned sheep died unexpectedly at the age of two years and 10 months. The cause of death was unknown and the carcass was quickly cremated as it was decomposing.

  6. Why Clone a Sheep? • Dolly the sheep, was produced at the Roslin Institute as part of research into producing medicines in the milk of farm animals.

  7. Why Clone a Sheep? • Researchers have managed to transfer human genes that produce useful proteins into sheep and cows, so that they can produce, for instance, the blood clotting agent factor IX to treat haemophilia or alpha-1-antitrypsin to treat cystic fibrosis and other lung conditions.
