The various classes of riboswitches discovered so far are differentiated by their respective '''ligands'''. Every class of riboswitch is characterized by an aptamer (binding site) domain, which provides the site for ligand binding, and an expression platform that undergoes conformational change. The sequences and structures of aptamer domains are highly conserved, and therefore exhibit little variation among riboswitches belonging to the same class. | The various classes of riboswitches discovered so far are differentiated by their respective '''ligands'''.
