Scope note: Cadenas cortas de ARN, de 100 a 300 nucleótidos, que abundan en el núcleo y suelen formar complejos con proteínas en las snRNP (RIBONUCLEOPROTEÍNAS NUCLEARES PEQUEÑAS). Muchos intervienen en el procesamiento de precursores del ARN mensajero; otros, los ARNsno (ARN NUCLEOLAR PEQUEÑO) participan en el procesamiento de precursores del ARN ribosómico.

Scope note: 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.
