small nuclear RNA
Let an agent explain small nuclear RNAs, relay their role in splicing, the snRNP complexes and links to disease from molecular biology sources, describe the named genes, and distinguish small nuclear RNA from small nucleolar RNA, microRNA, messenger RNA and transfer RNA.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

What it is Filled
A class of short non-coding RNA molecules found in the nucleus of eukaryotic cells, about 100 to 300 nucleotides long, that play key roles in processing other RNAs, especially the spliceosomal small nuclear RNAs U1, U2, U4, U5 and U6 that help remove introns from messenger RNA during splicing, with the registry aliases naming specific genes such as RNU4ATAC, RNU2-1 and RNU6-1; small nuclear RNAs combine with proteins to form small nuclear ribonucleoproteins or snRNPs, and mutations in some, such as RNU4ATAC, cause rare genetic disorders. They differ from small nucleolar RNAs and microRNAs.
Why it exists Filled
Let an agent explain small nuclear RNAs, relay their role in splicing, the snRNP complexes and links to disease from molecular biology sources, describe the named genes, and distinguish small nuclear RNA from small nucleolar RNA, microRNA, messenger RNA and transfer RNA.
