pub const RNA: IsotopeModel;Expand description
RNA — the mean of the four ribonucleotide chain residues (a nucleoside monophosphate less one water, the unit a phosphodiester chain repeats):
| residue | formula | monoisotopic |
|---|---|---|
| A | C₁₀H₁₂N₅O₆P | 329.05252 |
| C | C₉H₁₂N₃O₇P | 305.04129 |
| G | C₁₀H₁₂N₅O₇P | 345.04743 |
| U | C₉H₁₁N₂O₈P | 306.02530 |
Unweighted mean: C₉.₅ H₁₁.₇₅ N₃.₇₅ O₇ (P₁) per 321.2916 Da. Unweighted because base composition is sequence-specific; weight it yourself with a custom model if you know the organism’s rRNA composition.
