It begins with the unzipping of the double helix by
helicases. Unzipping forms y-shaped replication forks
exposing promoter regions (TATA regions) where the initiator proteins and factor bind to
the regions of DNA. A primer also
attaches to the region. DNA polymerase then
binds to the regions and begins adding DNA nucleotides
to the 3’ end of the primer based on the nucleotides on the template strand. Topoisomerase continues to unwind the DNA as the
polymerase progresses to the end of
replication.
