A) Dolly was genetically identical to the egg- cell donor.
B) Dolly was cloned by fusing the nuclei from two separate eggs harvested from the same individual.
C) Dolly was cloned by fusing an egg with an embryonic stem cell.
D) Dolly was infertile, which indicated incomplete nuclear reprogramming.
E) Dolly was cloned by using a differentiated cell fused to an egg from another breed of sheep.

Question

Quizplus · Accepted Answer

Dolly the sheep was cloned by using a differentiated somatic cell from a Finn Dorset sheep, which was fused with an enucleated egg cell from a Scottish Blackface sheep, effectively making her genetically identical to the somatic cell donor, not the egg-cell donor. This process demonstrated that a differentiated cell could reprogram to an embryonic state and develop into a new organism.
