An mRNA whose translation is controlled by binding of a metabolic end product such as flavin adenine dinucleotide or adenosylcobalamin is called a____________.

Question

Quizplus · Accepted Answer

This type of mRNA is called a riboswitch, which is an RNA element that controls gene expression by binding to a small molecule, such as a metabolite, and changing its structure to affect translation. Ribozymes are catalytic RNA molecules, miRNAs are small RNA molecules that regulate gene expression post-transcriptionally, and regulatory RNAs are a broad term that includes various types of RNA molecules that are involved in gene expression regulation.
