| A | B |
| DNA replication | Process of making a copy of DNA |
| DNA helicase | An enzyme that opens up the double helix by breaking the hydrogen bonds between the bases |
| DNA polymerase | An enzyme that adds nucleotides to the exposed nitrogenous bases according the base-pair rules |
| Synthesis | Stage of the cell cycle in which DNA replication takes place |
| DNA Ligase | An enzyme that creates bonds between deoxyribose and a phosphate group (sugar-phosphate backbone) |
| Primase | An enzyme that creates a short piece of RNA on the DNA template for the DNA polymerase to begin replication |
| SSBP | Single stranded binding proteins, help the unwounded DNA stabilize |
| DNA template | the strand used to make a complimentary copy |
