11. Which of the following statement regarding eukaryotic RNA polymerase II is not true ? (A) The zipper of Rpb1 collaborates with the lid to initiate dissociation of the DNA-RNA hybrid. (B) The lid of Rpbl interacts with DNA-RNA hybrid & maintains the hybrid dissociation. (C) The pore 1 of RNA polymerase II is the place for extrusion of the 3'end of RNA when RNA polymerase II backtracks. (D) Alpha-amanitin blocks translocation after a phosphodiester bond forms in transcription, without blocking nucleotide entry. (E) Bridge helix lies next to the active center of RNA polymerase II & flexing this helix may function in translocation during transcription.
