5.
What is the function of DNA polymerase in the process of PCR?
YOUR CORRECT
ANSWER ANSWER
It separates the two DNA strands so that replication may occur.
It recognizes the primers and uses the available dNTPs to replicate the template
DNA sequence.
It synthesizes primers and uses the available dNTPs to replicate the template
DNA sequence.
It links the products of PCR together to generate a complete strand.
