Which metaphors correctly compare chromatin remodeling and microRNA function?
A)A hammer and a nail
B)An on/off switch and a dimmer switch
C)An elevator and a submarine
D)An activator and a repressor

Question

Quizplus · Accepted Answer

Both chromatin remodeling and microRNA function involve regulating gene expression. Chromatin remodeling can be compared to an on/off switch because it can activate or silence genes by altering the accessibility of DNA to transcription factors. Similarly, microRNA function can be compared to a dimmer switch because it can fine-tune gene expression by downregulating mRNA and subsequently protein levels. The other options listed do not accurately reflect the similarities between these two processes.
