What is RNA Base Modification?
Modified bases, also known as rare bases, are relatively rare in nucleic acid molecules. However, they are naturally occurring and not artificially synthesized. They are formed by methylation, acetylation, hydrogenation, fluorination and sulfuration after nucleic acid transcription.
The modified bases are mostly methyl derivatives of the major bases. For example: 5-methylcytidine, 5,6-didehydrouridine, etc. In addition, there is a special nucleoside: pseudouridine nucleoside is due to the different way of base and ribose connection, that is, the C-C glycosidic bond formed by the carbon of uracil 5 position and nucleoside. tRNA contains more modified bases, and some tRNAs contain rare bases up to 10%.
