of embryonic cells. The same technique, using somatic cells, was later used to create Dolly the Sheep
. Their experiment was the first successful nuclear transplantation performed in metazoans.
Cloning
Cloning in biology is the process of producing similar populations of genetically identical individuals that occurs in nature when organisms such as bacteria, insects or plants reproduce asexually. Cloning in biotechnology refers to processes used to create copies of DNA fragments , cells , or...

by nuclear transfer
Nuclear transfer
Nuclear Transfer is a form of cloning. The steps involve removing the DNA from an oocyte , 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...

Dolly the Sheep
Dolly was a female domestic sheep, and the first mammal 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 near Edinburgh in Scotland...
