Molecular weights of RNA and DNA nucleosides
| DNA | RNA | |
|---|---|---|
| G + C | G + C | 494.4 | 526.4 (32D) |
| G + C > A + T | 494.4 > 493.4 (1D) | NA |
| G + C > A + U | NA | 526.4 > 511.4 (15D) |
| T > C | U > C | 242.2 > 227.2 (15D) | 244.2 > 243.2 (1D) |
| G > A | G > A | 267.2 > 251.2 (16D) | 283.2 > 267.2 (16D) |
Note: Only MWs of nucleosides are calculated and U is 1 Daltons heavier than C. The MW differences between nucleosides compared are shown in parentheses. D, Dalton.
