Do Clones Exist?

Do Clones EXIST? Or is it possible?
The Sheep above is a clone. Yes, Her name was Dolly. Wikipedia has some Information about Dolly
From Wikipedia

Dolly (5 July 1996 – 14 February 2003) was a female domestic sheep remarkable in being the first mammal to be cloned from an adult somatic cell, using the process of nuclear transfer.[1][2]Ian Wilmut, Keith Campbell and colleagues at the Roslin Institute near Edinburgh in Scotland. She was born on 5 July 1996 and she lived until the age of six.[3] She has been called "the world's most famous sheep" by sources including BBC News and Scientific American.[4][5] She was cloned by

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 part of the body could recreate a whole individual. As Dolly was cloned from part of a mammary gland, she was named after the famously busty country western singer Dolly Parton.[6]

Ok What is Nuclear Transfer? I know it's a way of cloning!

Yes, Wikipedia has the answers too!
Nuclear Transfer is a form of cloning. The steps involve removing the DNA from an oocytenucleus
(unfertilized egg), and injecting the nucleus which contains the DNA to be cloned. In rare instances, the newly constructed cell will divide normally, replicating the new DNA while remaining in a pluripotent state. If the cloned cells are placed in the uterus of a female mammal, a cloned organism develops to term in rare instances. This is how Dolly the Sheep and many other species were cloned.

Do we really need clones?
