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.
