DNA Replication
occurs
in this phase of
the cell cycle
What is
interphase?
This enzyme proofreads
the new strand.
What is DNA polymerase?
This enzyme unwinds
the DNA
helix before replication.
What is DNA
helicase?
This enzyme adds
nucleotide to
the new strand
What is DNA
polymerase?
The reason that
DNA is replicated
