Which of the following is not true?
A) The mechanism of activation of eukaryotic genes involves addition and removal of phosphate residues from some of the transcription factors.
B) In plants, there are 5 RNA polymerases.
C) RNA Pol IV is the primary RNA synthesizer in plants
D) Of the RNA Polymerases in eukaryotes, Pol II is the most extensively studied.

Question

Quizplus · Accepted Answer

RNA Pol IV is not the primary RNA synthesizer in plants; RNA Pol II is the primary enzyme responsible for synthesizing messenger RNA (mRNA) in eukaryotes, including plants. RNA Pol IV in plants is involved in siRNA synthesis and plays a role in RNA-directed DNA methylation, not in the primary synthesis of RNA as the question implies.
