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:
“Tomorrow in the offices the year on the stamps will be altered;
Tomorrow new diaries consulted, new calendars stand;
With such small adjustments life will again move forward
Implicating us all; and the voice of the living be heard:
“It is to us that you should turn your straying attention;
Us who need you, and are affected by your fortune;
Us you should love and to whom you should give your word.””
—Philip Larkin (1922–1986)
