In 1997, the first clone sheep appeared, ewe Dolly, was the first animal to be cloned from an adult somatic cell, using the process of nuclear transfer. She was cloned by Ian Wilmut, Keith Campbell and colleagues at the Roslin Institute in Edinburgh, Scotland. The cell used as the donor for the cloning of Dolly was taken from a mammary gland, and the production of a healthy clone therefore proved that a cell taken from a specific body part could recreate a whole individual. More specifically, the production of Dolly showed that mature differentiated somatic cells in an adult animal's body could under some circumstances revert back to an undifferentiated pluripotent form and then develop into any part of an animal.
Reflection:
It's really amazing after I read about how did Dolly appeared, I cant believe that Dolly was made by adult somatic cell!!! also she same as Some idea come out of my brain, if Human also can cloned, I believe it will develop of human history, but problems come out, if people cloned success, all around the world only have one kind of people........:) I predict that the world will have more cloned animals because Dolly was a successfull cloned animal, scientist will follow that and they to create another.
