The DNA from the egg of a sheep was removed.The DNA from the udder cell was added to an egg cell.
Answer
A
A cell from the udder of a sheep was removed.
B
Developing cells were placed in another sheep.
C
Organisms with desirable traits were crossed.
D
The DNA from the egg of a sheep was removed.
E
The DNA from the udder cell was added to an egg cell.
Explanation
Dolly was cloned using a body cell from a sheep’s udder and an egg cell from another sheep. The egg’s DNA was removed, and the udder cell’s DNA was transferred into the egg. After the resulting cells began developing, the developing embryo was placed in a surrogate sheep. Crossing organisms with desirable traits was not part of this cloning process.
