Match List-I with List-II regarding the components of transcription in prokaryotes. List-I List-II A. Core RNA polymerase I. Initiation B. Sigma ( ) factor II. Elongation C. Rho ( ) factor III. Termination Choose the correct answer from the options given below:

Step-by-step solution

In prokaryotes, the core RNA polymerase enzyme is intrinsically responsible for catalysing the elongation phase of transcription (A-II). To initiate transcription, the core enzyme must associate transiently with the initiation factor, which is the sigma ( ) factor (B-I). For the termination of transcription, the RNA polymerase associates transiently with the termination factor, known as the rho ( ) factor (C-III). Therefore, the correct matching is A-II, B-I, C-III. Answer: A-II, B-I, C-III
