DNA polymerase III
primary replication enzyme - elongates a new nucleotide strand from the 3'- OH of the primer.
DNA polymerase I
removes the RNA nucleotides of the primers and replaces them with DNA nucleotides - carries out proofreading
synthesizes the RNA primers that provide the 3' OH group needed for DNA polymerase III to initiate DNA synthesis
unwinds the double helix by breaking the hydrogen bonding between the two strands at the replication fork
reduces DNA supercoiling and torsional strain that is created ahead of the replication fork by makine double-stranded breaks in the DNA and pasing another segment of the helix through the break before resealing it - also known as topoisomerase II
single-stranded binding proteins (SSB protein)
stabilizes single-stranded DNA prior to replication by binding to it, thus preventing the DNA from pairing with complementary sequences
