You want to design a drug that prevents transcription of mRNAs but does not affect transcription of other RNAs. What enzyme would you target?

B)RNA polymerase II
C)RNA polymerase III
D)ribozyme
E)methyl transferase

Question

RNA polymerase II is responsible for transcribing mRNA in eukaryotes. Therefore, targeting this enzyme will specifically inhibit mRNA transcription while leaving transcription of other RNAs (such as rRNA and tRNA) unaffected.
