↗ Small RNA molecules regulate gene expression by post-transcriptional gene silencing.
↗ Xist: the first long non-coding RNA regulating gene expression.
↗ Non-coding RNAs control epigenetic phenomena.
↗ Transcriptomics: most of the genome is transcribed at some point in time and space.
↗ Riboswitches bind cellular metabolites and control gene expression.
↗ Many mobile DNA elements use an RNA intermediate.
