If E.coli DNA polymerase III was able to initiate DNA synthesis opposite a single- stranded template,which molecules)would no longer be essential? A)single- stranded binding proteins B)DNA gyrase C)DNA ligase D)DNA polymerase I E)helicase

Question

DNA polymerase I is responsible for filling in gaps left behind after DNA synthesis by DNA polymerase III, but if DNA polymerase III could initiate synthesis on its own, then DNA polymerase I would no longer be essential. The other molecules are still needed for DNA replication.
