Somatic Cell Nuclear Transfer (SCNT) is a laboratory technique used in cloning. It involves taking the nucleus from a somatic cell, which is any cell in the body except sperm and egg cells, and transferring it into an egg cell that has had its nucleus removed. This process allows the egg to develop into an organism that is genetically identical to the donor of the somatic cell. SCNT has been used in various research applications, including the cloning of animals like Dolly the sheep, the first mammal cloned from an adult somatic cell. This technique raises ethical questions and has implications for fields such as regenerative medicine and conservation biology.
