Created by Rebeccca   8 terms   an enzyme that unwinds the
helix, and separates the two strands. This action requires ATP
An enzyme that prevents the tangling of the DNA as it unwinds
single strand binding proteins (SSBPs)  bind to the sugar-
phosphate backbone of a single-stranded DNA, preventing the
single stranded regions from paring back together  RNA Primase
a special RNA polymerase that makes short RNA primers that allow
DNA polymerases to work. A primer is required because there must
be a free 3' OH group available fro the addition of each
nucleotide.  DNA polymerase III  recognizes the RNA primer and
synthesizes DNA in the 5' to 3' direction  Okazaki fragments
leading and lagging strands  DNA polymerase I  removes the RNA
primers and replaces them with DNA   makes sure that the newly-
synthesized DNA is covalently-linked strand
