Final answer:
Some mRNAs from Listeria monocytogenes contain a "thermosensor" sequence that regulates translation in a temperature-dependent manner through the binding of small intracellular molecules and the formation of stem-loop structures.
Step-by-step explanation:
Some mRNAs from the bacterium Listeria monocytogenes contain a "thermosensor" sequence that can regulate translation in a temperature-dependent manner. This regulation occurs through the binding of small intracellular molecules to stabilize certain secondary structures of the mRNA molecule, influencing the completion of mRNA synthesis and protein synthesis. The formation of stem-loop structures at the 5' ends of bacterial mRNAs, such as riboswitches, also plays a role in temperature-dependent regulation of gene expression.
