Small Nucleolar RNA
Small nucleolar RNAs (snoRNAs) are a class of small RNA molecules 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 associated with pseudouridylation. SnoRNAs are commonly referred to as guide RNAs but should not be confused with the guide RNAs that direct RNA editing in trypanosomes.

Famous quotes containing the word small:
“Much wondering to see upon all hands, of wattles and woodwork made,
Your bell-mounted churches, and guardless the sacred cairn and the rath,
And a small and a feeble populace stooping with mattock and spade,
Or weeding or ploughing with faces a-shining with much-toil wet;
While in this place and that place, with bodies unglorious, their chieftains stood....”
—William Butler Yeats (1865–1939)
