Dolly is an advanced clone of a sheep, created through a scientific process called somatic cell nuclear transfer. In this process, the nucleus (the cell's control center) from an adult sheep's cell is transferred into an egg cell that has had its original nucleus removed. This egg then develops into an embryo and is implanted into a surrogate mother, resulting in a new sheep genetically identical to the original donor. Dolly demonstrated that mature cells can be reprogrammed to create an entire organism, providing insights into genetics and aging.
