Which statement is FALSE regarding the mediator protein in eukaryotic gene regulation?

Question

Quizplus · Accepted Answer

D) It enhances dephosphorylation of the RNA polymerase carboxy-terminal domain.
The mediator does not enhance dephosphorylation of the RNA polymerase II carboxy-terminal domain (CTD); rather, it is involved in the transition of RNA polymerase II from a pre-initiation complex to the initiation of transcription, which includes the phosphorylation of the CTD. The CTD must be phosphorylated for RNA polymerase II to transition into the elongation phase of transcription.
