Correct Answer
(D) RNA polymerase binds with Rho factor to terminate the process of transcription in bacteria.
Solution & Explanation
Answer: (D) RNA polymerase binds with Rho factor to terminate the process of transcription in bacteria. RNA polymerase associates with the termination-factor rho (ρ) to terminate transcription; the other options are wrong - the template (not coding) strand is copied, split genes are a eukaryotic feature, and in capping methyl guanosine triphosphate is added to the 5' (not 3') end. NCERT Ch 5, p.94, lines 11-13: "It associates transiently with initiation-factor (σ) and termination-factor (ρ) to initiate and terminate the transcription, respectively."
