A riboswitch can adopt different secondary structures to effect gene regulation depending on whether ligand is bound. This schematic is an example of a riboswitch that controls transcription.

RNA is able to control its own transcription, given the right trigger. See how the RNA-based riboswitch twists into a tangle in the presence of the right ligand.
