WebMar 9, 2024 · Likewise, RNA is chemically modified. Figure 8.3. 2 shows common modifications of bases in RNA. Methylation and subsequent hydroxylation to hydroxymethyl are common to both DNA and RNA. Methylation of DNA often represses the transcription of the DNA into RNA. Hence it has huge potential to alter gene transcription. WebRibonukleinska kiselina skraćeno RNK (eng.
