Why was 1996 a very important year for science?

In 1996, a major scientific breakthrough stunned the world. This was the year that the first mammal was successfully cloned from an adult cell.

What is cloning? Cloning is a process in which scientists extract the DNA from an animal cell, and implant it into an egg cell taken from another animal. Before implanting it, the DNA of the recipient cell is removed. This is how Dolly’s life began – from a single cell taken from the udder of her mother.

The DNA in her mother’s cell was removed, and transferred into the egg cell of another sheep. Five months later, Dolly was born, creating medical history.

It was Ian Wilmut, Keith Campbell, and their colleagues at the Roslin Institute in Edinburgh, Scotland who were responsible for this remarkable • achievement.
