La oveja Dolly

The video discusses the concept of artificial cloning, highlighting the initial challenges faced with malformed and prematurely dying animals. It then focuses on the breakthrough achieved in 1997 by scientists at the Rosslin Institute with the cloning of Dolly the sheep, the first successful clone from an adult mammal. The process involved nuclear transfer, where the nucleus of an adult sheep cell was inserted into an egg cell. Despite Dolly's premature death, her creation paved the way for advancements in genetic engineering, including the potential for human gene transfer to animals for medical purposes. The video also touches on the ethical debates surrounding cloning.
