Small nucleolar RNA

Small nucleolar RNAs (snoRNAs) are a class of non-coding small RNA molecules in the nucleolus that primarily guide chemical modifications of other RNAs, mainly ribosomal RNAs, transfer RNAs and small nuclear RNAs. There are two main classes of snoRNA, the C/D box snoRNAs, which are associated with methylation, and the H/ACA box snoRNAs, which are…
