WebSmall nuclear RNA (snRNA)[edit edit source] Small nuclear RNAs (snRNA) are the small RNA molecules that are found in the nucleus of eukaryotic cells. They are usually 300 nucleotides or smaller and the nucleus contains more than just snRNA. The function of snRNA was discovered before the ribozyme enzyme by a few years.

WebA non-coding RNA, or an ncRNA, as it is abbreviated, is a functional RNA molecule that actually skips this last step and is not translated into a protein. In other words, they just go directly from transcription into an RNA molecule and then go off to perform any number of vital functions within the cell.
