| adenine and guanine | nitrogenous bases that have a double ring of carbon and nitrogen. |
| cytosine and thymine | nitrogenous bases that have a single ring of carbon and nitrogen. |
| chargaffs rule | equal amounts of adenine bonds with thymine and equal amount of guanine bonds with cytosine. |
| DNA replication | The process by which DNA is copied in a cell before the cell divides by mitosis, meiosis or binary fission |
| helicase | the enzyme that separates the DNA strand |
| replication fork | Y-shaped region that results when the two strands separate is called: |
| DNA polymerase | the enzyme that adds complementary nucleotides that are inside the nucleus to each section of the DNA strand. |
| mutation | DNA polymerases proofreads the new strands, but for every billion, one can cause an error called a |

| repressor | prevents the translation until the protein needs to be produced. |
| promoter | tells you where to start |
