Question

multiple choice
one way to clone an organism is to transfer the nucleus of a cell taken from animal a, place it into an egg from animal b whose nucleus has been removed, and then implant it into a surrogate mother, animal c. the cloned animal would be identical to:
○ animal b because the egg with its nucleus removed contains dna
○ animal a because the nucleus contains dna.
○ none of the animals above because an offspring will have half of their dna in common with the mother and half with the father.
○ animal c because this was the mother of the cloned animal.

Explanation:

Cloning via somatic cell nuclear transfer means the cloned organism inherits the full nuclear DNA from the donor cell (animal A). The enucleated egg from animal B only provides cytoplasm, and the surrogate mother (animal C) only carries the embryo, contributing no nuclear DNA. Thus, the clone is genetically identical to animal A.

Answer:

animal A because the nucleus contains DNA.
