Non-Coding RNAs

Created by: Franck Vazquez

A Non-Coding RNA, abbreviated ncRNA, is a ribonucleic acid (RNA) molecule which is either not translated into a protein or can be translated into a protein but is biologically active in its RNA form.

Major ncRNA families include ribosomal RNAs (rRNAs), transfer RNAs (tRNAs), small nuclear RNAs (snRNAs), small nucleolar RNAs (snoRNAs), PIWI-interacting RNAs (piRNAs), small interfering RNAs (siRNAs), microRNAs (miRNAs), or long non-coding RNAs (lncRNAs) like the prototypic examples XIST or HOTAIR .
