Question:
All of the following are functions of DNA polymerase in DNA
replication except
A) covalently adding nucleotides to the new strands.
B) proofreading each added nucleotide for correct base
pairing.
C) replacing RNA primers with DNA.
D) initiating a polynucleotide strand.
E) none of the above
