Dolly the Sheep

By Jim, Matti, Carter, and Charlie

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.

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.

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.

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.

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.

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.
