The most frequent way in which small regulatory RNA molecules exert their effects is by
A) base pairing with other RNA molecules that have regions of complementary sequence.
B) binding to a repressor and repressing enzyme transcription.
C) acting as an inducer that then binds to an activator protein to allow transcription to proceed.
D) signal transduction.

Question

Quizplus · Accepted Answer

Small regulatory RNA molecules predominantly exert their effects by base pairing with other RNA molecules that have regions of complementary sequence. This can result in various effects, including blocking translation, promoting degradation, or stabilizing the RNA target.

Option B is incorrect because small regulatory RNA molecules do not bind to repressors themselves, but rather bind to the target RNA molecule directly.

Option C is also incorrect because small regulatory RNA molecules do not act as inducers or bind to activator proteins to allow transcription to proceed.

Option D is too general and does not accurately describe the mechanism of small regulatory RNA molecules.
