D) The phosphorylated form of the enzyme is necessary for the elongation of mRNA.

Question

Quizplus · Accepted Answer

The phosphorylated form of Pol II is necessary for the elongation of mRNA, as it allows the enzyme to move along the DNA template and add nucleotides to the growing mRNA molecule. The unphosphorylated form of Pol II is inactive and cannot carry out transcription. Therefore, option D is the correct statement about the enzyme Pol II.
