Small molecules that bind directly to mRNAs and effect transcription or translation are binding to regions of the mRNA known as
A)Shine-Dalgarno sequences.
B)operator regions.
C)riboswitches.
D)ribozymes.
E)allosteric sites.

Question

Quizplus · Accepted Answer

Riboswitches are regions within an mRNA molecule that can bind small molecules directly. This binding can influence the mRNA's structure, thereby affecting the gene's expression by altering transcription, translation, or degradation processes. Shine-Dalgarno sequences, operator regions, ribozymes, and allosteric sites have different roles in gene expression and enzyme regulation.
