Proteins in DNA Replication

All enzymes are proteins, but not all proteins are enzymes •Helicase - unzips the DNA double helix •Topoisomerase - relieves/prevents super coiling •Single Stranded Binding Protein - proteins that bind a single strand of the DNA to prevent it from closing back up •RNA primase - makes the RNA primer (RNA primer is needed for DNA polymerase to start elongation) •DNA polymerase III - main enzyme that elongates the new strand •DNA polymerase I - mainly removes the RNA primer and replaces it with a DNA sequence •Ligase - seals the gaps between okazaki fragments
