Quizplus · Accepted Answer

A riboswitch is a sequence in an mRNA molecule that regulates its translation by binding to a specific small molecule, causing a conformational change in the mRNA that affects translation efficiency. Riboswitches are found in both prokaryotic and eukaryotic cells. The other choices (operon, operator, promoter, and regulator protein) are all involved in gene expression regulation in prokaryotes, but they do not directly regulate translation of mRNA.
