C)allows us to study small amounts of DNA available in ancient skeletons.
D)all of the above

Question

Quizplus · Accepted Answer

PCR is a powerful tool for genetic analysis that allows us to amplify small sequences of DNA for study, even if the sample size is very small, such as DNA obtained from ancient skeletons. This allows us to explore the origins and movements of populations using genetic methods. Therefore, all of the options A, B, and C are correct.
