The enzyme that inserts the correct bases in a growing nucleotide chain in a replicating DNA molecule is
A)RNA polymerase.
B)DNA ligase.
C)DNA polymerase.
D)helicase.

Question

Quizplus · Accepted Answer

DNA polymerase is responsible for adding the correct bases (A, T, C, G) to a growing nucleotide chain during DNA replication. RNA polymerase is involved in transcription (the process of making RNA from DNA) and DNA ligase is involved in sealing the gaps between the Okazaki fragments on the lagging strand during DNA replication. Helicase is responsible for unwinding the double-stranded DNA molecule during replication.
