The RNA polymerase is only capable of catalysing the process of elongation, thus, statement I is correct. RNA polymerase associates transiently with initiation-factor (σ) and termination-factor (ρ) to initiate and terminate the transcription. Thus, statement II is incorrect.
Given below are two statements regarding RNA polymerase in prokaryotes. Statement I : In prokaryotes, RNA polymerase is capable of catalysing the…

Given below are two statements : Statement I : In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable. Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repairing mechanism.
