Where is the next nucleotide added to the growing chain during DNA replication?

Question

Quizplus · Accepted Answer

The next nucleotide is added to the 3' hydroxyl group of the previous nucleotide, so choice A is correct. Choice B is incorrect because a phosphate group is not involved in forming the bond between nucleotides during DNA replication. Choices C and D are incorrect because they refer to the opposite end of the nucleotide and are not involved in forming the phosphodiester bonds that connect nucleotides in a growing DNA chain.
