DNA-Basen
| freie Base | Nukleosid | Nukleotid |
|---|---|---|
| Adenin (A) | Adenosin | Adenosinmonophosphat (AMP) |
| Guanin (G) | Guanosin | Guanosinmonophosphat (GMP) |
| Cytosin (C) | Cytidin | Cytidinmonophosphat (CMP) |
| Thymin (T) | Thymidin | Thymidinmonophosphat (TMP) |
| Uracil (U) | Uridin | Uridinmonophosphat (UMP) |
Nukleosid= Base + Zucker
Nukleotid= Base + Zucker + Phosphat
