Preferred Label : rna, small nuclear;
MeSH definition : Short chains of RNA (100-300 nucleotides long) that are abundant in the nucleus and
usually complexed with proteins in snRNPs (RIBONUCLEOPROTEINS, SMALL NUCLEAR). Many
function in the processing of messenger RNA precursors. Others, the snoRNAs (RNA,
SMALL NUCLEOLAR), are involved with the processing of ribosomal RNA precursors.;
