(B) Among three RNAPs, RNAP II is insensitive to alpha-amanitin.
(C) The 28S, 18S and 5S ribosomal RNA are synthesized by RNAP I, while tRNA and other small RNA are synthesized by RNAP III.
(D) Rpb5, Rpb7, Rpb9, Rpb10 and Rpb12 are common subunits for all three RNAPs.
(E) RNAP IIA contributes to transcription elongation, while RNAP IIO is involved in the formation of pre-initiation complex.
