why cloning doesn't work - dolly the sheep
Dolly the sheep, as the first mammal to be cloned from an adult cell, is by far the world's most famous clone. However, cloning has existed in nature since the dawn of life.From asexual bacteria to âvirgin birthsâ in aphids, clones are all around us and are fundamentally no different to other organisms.nimal cloning from an adult cell is much more difficult than from an embryonic cell. 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.
