DNA contains the template needed to copy itself, but it has no catalytic activity in cells. What catalyses the formation of phosphodiester bonds between adjacent nucleotides in the DNA polymer being formed during DNA replication?
A) ribozymes
B) DNA polymerase
C) ATP
D) RNA primers

Question

Quizplus · Accepted Answer

DNA polymerase is the enzyme responsible for catalyzing the formation of phosphodiester bonds between the adjacent nucleotides in the DNA polymer being formed during DNA replication. Ribozymes are RNA molecules with catalytic activity, but they are not involved in DNA replication. ATP is used as an energy source in various cellular processes, but it is not directly involved in phosphodiester bond formation in DNA replication. RNA primers are short RNA sequences that are synthesized by primase to initiate DNA replication, but they are not involved in catalyzing the formation of phosphodiester bonds between adjacent nucleotides during DNA replication.
