B) DNA polymerase
C) ATP
D) RNA primers

Quizplus · Accepted Answer

DNA polymerase catalyzes the formation of phosphodiester bonds between adjacent nucleotides in the DNA polymer being formed during DNA replication. Ribozymes are RNA molecules that have catalytic activity, but they are not involved in DNA replication. ATP is used as an energy source and is not directly involved in forming phosphodiester bonds in DNA replication. RNA primers are used to initiate DNA synthesis during DNA replication, but they are not directly involved in forming phosphodiester bonds between nucleotides.
