Question

Quizplus · Accepted Answer

Therapeutic cloning involves using somatic cells to create embryonic stem (ES) cells, but not creating whole individuals. This is accomplished by injecting a somatic cell nucleus into an enucleated egg, allowing it to divide and develop into a blastocyst from which ES cells can be extracted. Reproductive cloning, on the other hand, is the creation of a fully developed organism through the use of cloning techniques. Therefore, B and C are incorrect. D is incorrect because it includes option C, which is incorrect. Therefore, the correct answer is A.
