Animal cloning

The story of Britain's first cloned pet dog by a Korean company has raised many questions and serious ethical concerns. Is it a step too far?

Cloned animalsThere are 3 types of cloning:

1. Gene cloning or DNA cloning - produces copies of segments of DNA

2. Reproductive cloning - produces copies of the whole animal

3. Therapeutic cloning - involves the process of somatic cell nuclear transfer (SCNT) to create tissue to potentially treat diseases and damaged organs
