In this essay you will learn how Dolly was created, about her life, and the scientific advances she set in motion.

Dolly the sheep was through a process called “Somatic Nuclear Transfer.” To perform this process you need many steps. First you must remove the nucleus from an egg cell and insert it into an egg cell from a different sheep. (Freudenrich) To perform this step Ian Wilmut used a very small and sharp needle and extracted the nucleus from the Finn Dorsett sheep, which is the white sheep, and inserted it in to a Black faced sheep’s unfertilized egg cell.
