Accepted Answer

In March 1997,Scottish investigators announced they had successfully cloned a Dorset sheep,which they named Dolly.An adult nucleus was placed in an enucleated egg cell.The donor cell had been starved,which caused it to stop dividing and go into a resting stage (the G0 stage of the cell cycle).The G0 nucleus was amenable to cytoplasmic signals for initiation of development.
