The most frequent way in which small regulatory rna molecules exert their effects is by the most frequent way in which small regulatory rna molecules exert their effects is by binding to a repressor and repressing enzyme transcription. signal transduction. base pairing with other rna molecules that have regions of complementary sequence. acting as an inducer that then binds to an activator protein to allow transcription to proceed.
For the answer to the question above, I believe the answer here is that you must base the pairing with the other RNA molecules that have regions of the complementary sequence.
