What two important domains within a riboswitch involve the ligand-binding site? / What two important domains within a riboswitch involve the ligand-binding site? A site and B site conformation and anticonformation aptamer and expression platform B site and C site alpha and beta

The correct answer for the question that is being presented above is this one: "conformation and anticonformation." The two important domains within a riboswitch that involve the ligand-binding site are conformation and anticonformation. Riboswitch refers to the regulatory segment of a messenger RNA molecule that binds a small molecule.
