Steps of DNA Replication
Like all cellular processes,
replication of DNA is mediated by enzymes, such as DNA polymerase III (Pol
III). These enzymes must function to copy DNA as fast and as accurately
The helicase enzyme unwinds
DNA, at the origin of replication. Two replicating forks are created.
This reaction needs ATP. The exposed single-stranded DNA is protected
by single-strand binding proteins (ssb).
