Somatic cell nuclear transfer can make clones

Dolly (5 July 1996 – 14 February 2003) was a sheep, remarkable in being the first mammal to be cloned from an adult somatic cell.

A somatic cell is a regular body cell, not an egg cell. The nucleus of the somatic cell was removed and put into an unfertilised egg cell. The process is called somatic cell nuclear transfer. She was cloned at the Roslin Institute in Edinburgh, Scotland. It took 277 attempts to create Dolly. The success rate when cloning animals is very low.
