Join us as we uncover the remarkable journey of Dolly the Sheep and the lessons we can learn from her extraordinary existence.
What Was the Cloning Process Behind Dolly the Sheep?
The cloning of Dolly the Sheep was a groundbreaking achievement that utilized a technique known as somatic cell nuclear transfer (SCNT). This intricate process involved several key steps:
- Cell Selection: Scientists selected a somatic cell, which is any cell in the body excluding sperm and egg cells, from a 6-year-old Finn Dorset ewe.
- Nuclear Transfer: The nucleus of the somatic cell, containing the genetic material, was extracted and inserted into an enucleated egg cell (an egg cell with its nucleus removed).
- Stimulation: The egg cell was stimulated to begin dividing and developing into an embryo.
- Embryo Implantation: The embryo was then implanted into a surrogate mother, a Scottish Blackface ewe.
- Birth of Dolly: On July 5, 1996, Dolly was born, marking a significant milestone in the field of genetics and cloning.
