| Prerequisite material for replication | Helicase, DNA ligase, DNA polymerase I, DNA polymerase III, RNA primase |
| Prerequisite material for replication | Parent DNA strand |
| Helicase | unwinds DNA |
| Helicase | breaks the hydrogen bonds between the bases |
| Helicase | forms replication fork |
| template | original single polymer, DNA strand |
| DNA polymerase III | binds new nucleotides to each other by condensation reactions |
| DNA polymerase III | forms covalent bonds between nucleotides |
| DNA polymerase III | new nucleotide added to 3' carbon of existing strand |
| RNA primase | adds short RNA primer to template strand |
| RNA primase | allows DNA polymerase III to bind |
| DNA polymerase I | removes RNA primer |
| DNA polymerase I | replaces RNA primer with DNA nucleotides |
| DNA ligase | anneals Okizaki fragments to one another |
| DNA ligase | attaches to short DNA polymers to each other covalently |
| DNA nucleotide | missing oxygen atom at 2' carbon |
| RNA nucleotide | hydroxyl group located at 2' carbon |
