How would you accurately summarize the process used to make Dolly the sheep?
A)Mitochondrial DNA was taken from one female and injected into the mammary glands of another female.
B)A sheep embryo was produced by in vitro fertilization.At an early stage,the cells of the embryo were separated,and each cells was put into a surrogate sheep mother.
C)A mammary cell of one sheep was fused with an enucleated egg of another sheep.The resulting diploid embryo was placed in a surrogate sheep mother.
D)A set of twins - one male and one female - were mateD.Since the twins had identical DNA,their lamb was a clone.
E)The sheep to be cloned was given a drug that induced the cells of her ovary to divide by binary fission.The resulting diploid eggs did not need to be fertilized,and were used to produce sheep embryos,including Dolly.

The process used to make Dolly the sheep involved taking a mammary cell from one sheep and fusing it with an enucleated egg from another sheep. The resulting embryo, which was diploid, was then placed in a surrogate sheep mother. This is known as somatic cell nuclear transfer, and it was the first successful instance of cloning a mammal from an adult cell.
