Final answer:
In the process of attenuation, riboswitches can change conformation by binding specific effectors, influencing the completion of transcription and translation.
Step-by-step explanation:
In the process of attenuation, the level of an amino acid indirectly affects the conformation of the leader region. However, some leaders can change conformation by binding a specific effector. These leaders are known as riboswitches. Riboswitches are small regions of noncoding RNA found within the 5' end of certain mRNA molecules. They can bind to small intracellular molecules, influencing the formation of stem-loop structures and regulating the completion of transcription and translation.
