| Adenine | nitrogen base that pairs with Thymine |
| Amino Acid | chemicals that make up proteins |
| Chargaff | Scientist who discivered that the amount of adenine equals the amount of thymine |
| chromosome | rodlike structures within the nucleus that contain dna |
| conjoined | identical twins whose cell fails to split 12 days post conception |

| Franklin | Scientist who took the first images of DNA |
| fraternal | twins that are formed from 2 unique egg cells |
| gene | a portion of the DNA strand that determines a specific trait |
| guanine | nitrogen base that pairs with cytosine |
