Dolly the Sheep

The video discusses the concept of artificial cloning, highlighting the challenges faced in early attempts, such as birth defects. It focuses on the breakthrough achieved by scientists at the Roslyn Institute in 1997 with the cloning of Dolly the sheep. The process involved transferring the nucleus of an adult sheep cell into an egg cell. Dolly's creation raised ethical concerns due to her premature aging and early death. Despite these issues, the technology has potential applications in medicine, such as producing human proteins in livestock milk and possibly cloning human organs for transplants.
