Assuming 100% reaction efficiency, how many DNA copies are created after the completion of four complete PCR cycles? Correct Answer: 16 What is the function of DNA polymerase in the process of PCR? Correct Answer: It recognizes the primers and uses the available dNTPs to replicate the template DNA sequence. What are possible blood types of the parents of a patient with blood type AB?
