The function of the DNA polymerase is to catalyze
A) the addition of deoxynucleotides.
B) the formation of RNA primers.
C) the addition of ribonucleotides.
D) hydrogen bonding between complementary base pairs.

Question

Quizplus · Accepted Answer

DNA polymerase is an enzyme responsible for synthesizing new DNA strands. It does this by adding deoxynucleotides (the building blocks of DNA) to the growing strand, which are complementary to the existing strand. Therefore, choice A is the correct answer. B is incorrect because RNA primers are added by a different enzyme called primase, C is incorrect because DNA polymerase does not use ribonucleotides, and D is incorrect because while DNA polymerase does help stabilize the hydrogen bonds between base pairs, its main function is to add the nucleotides themselves.
