Which of the following is NOT a reason for the high fidelity of the newly synthesized DNA molecule?
A) The hydrogen bonding between purines and pyrimidines is stable.
B) The DNA polymerase is unlikely to form bonds between nucleotides if they are mismatched.
C) The DNA polymerase has exonuclease functions.
D) The DNA polymerase has the ability to change the structure of the base in order to form the correct bond.

The DNA polymerase does not have the ability to change the structure of the base in order to form the correct bond. Rather, it selects the appropriate nucleotide to match with the template based on its complementary base pairing, and it has proofreading capabilities (through exonuclease activity) to remove any incorrect nucleotides that may have been added.
