Dolly the sheep, the first mammal to be cloned from an adult somatic cell, is notable for several key reasons:
-
Cloning: Dolly was created using a technique called somatic cell nuclear transfer (SCNT). This involved taking the nucleus from an adult somatic cell (specifically a mammary gland cell) and transferring it into an enucleated egg cell.
-
Birth and Life: Dolly was born on July 5, 1996, and lived for about six years. She was raised at the Roslin Institute in Scotland.
-
Genetic Identity: Dolly was genetically identical to the sheep from which her somatic cell was taken. This made her a clone.
-
Health Issues: Dolly faced several health issues during her life, including arthritis and a progressive lung disease, which raised concerns about the long-term health and aging of cloned animals.
-
Significance: Dolly's birth had a significant impact on the fields of genetics, cloning, and biotechnology, sparking discussions about the ethical implications and potential applications of cloning technology.
