Increasing ________ will decrease the amount of mRNA transcript within a cell for a constitutively active gene.
A) ribonuclease activity only
B) RNA polymerase activity only
C) siRNA concentration only
D) ribonuclease activity and siRNA concentration only
E) ribonuclease activity, RNA polymerase activity and siRNA concentration

Question

Quizplus · Accepted Answer

Ribonuclease activity and siRNA concentration can both degrade mRNA transcripts, leading to a decrease in the amount of mRNA within a cell. RNA polymerase activity, on the other hand, is required for the transcription of the gene and increasing it would lead to an increase in mRNA transcription. Therefore, increasing ribonuclease activity and siRNA concentration would be the best choice to decrease the amount of mRNA transcript for a constitutively active gene.
