Question

Quizplus · Accepted Answer

Chromatin remodeling can be compared to an on/off switch that regulates gene expression by opening or closing the chromatin structure. Similarly, microRNA function can be compared to a dimmer switch that fine-tunes gene expression by reducing the amount of mRNA available for translation. Both compare to switches, and option B compares the regulatory mechanisms that control gene expression to switches.
