DNA polymerase is responsible for the addition of nucleotides to the free 3' end of the RNA primer, resulting in elongation of the newly forming daughter DNA strand. RNA primase is the enzyme that makes the RNA primer during the replication process. Helicase is the enzyme that unzips the double helix, giving rise to the replication fork. RNA polymerase is involved in the process of transcription and not replication.
