Among the structurally simplest riboswitches are the two so-called purine riboswitches, one of which responds to guanine, and the other to adenine. The accompanying diagram shows a guanine riboswitch. Base-pairing between free guanine and a particular cytosine residue within the aptamer determines the riboswitch conformation. a. What condition in the cellular environment would favor each of the riboswitch configurations?
