DNA polymerase δ is responsible for filling the gap left by the nucleases that digest the primer and the short DNA segment added to it by polymerase δ. DNA polymerase α is involved in initiating DNA synthesis, but not in gap filling. DNA polymerase β is involved in DNA repair, but not in normal DNA replication. RNase H1 is involved in removing RNA primers, but not in gap filling.
