DNA polymerase lengthens a polynucleotide strand by

Question

Quizplus · Accepted Answer

DNA polymerase lengthens a polynucleotide strand by covalently linking new nucleotides to a previously existing strand. This is achieved by base pairing between complementary nucleotides and formation of phosphodiester bonds between the 3' hydroxyl group of the existing nucleotide and the 5' phosphate group of the incoming nucleotide. This process continues until the entire length of the strand is replicated. Choices A, B, C, and D do not accurately describe the mechanism of DNA polymerase during replication.
