helicaseunwinds DNA template at replication fork
single-stranded binding proteinsprevents strands from reannealing
DNA topoisomerasescreate a nick in the helix to relieve supercoils created during replication
primasemakes an RNA primer on which DNA pol III can initiate replication
DNA polymerase III(prokaryotic only) elongates leading strands by adding deoxynucleotides to the 3' end; elongates lagging strand until it reaches primer of preceding fragment
DNA polymerase I(prokaryotic only) degrades RNA primer and fills in the gap with DNA
