Nucleotide = Phosphate group + Sugar + Nitrogenous base
Hydrolysis pathway:
- DNA → Nucleotide → Phosphoric acid + Nucleoside → Sugar (2-deoxyribose) + Purine/Pyrimidine base
- RNA → Nucleotide → Phosphoric acid + Nucleoside → Sugar (Ribose) + Purine/Pyrimidine base
Nitrogen Bases:
| Type | DNA bases | RNA bases |
|---|---|---|
| Purines (double ring) | Adenine (A), Guanine (G) | Adenine (A), Guanine (G) |
| Pyrimidines (single ring) | Cytosine (C), Thymine (T) | Cytosine (C), Uracil (U) |
