Read the following statements carefully: (I) In bacteria, a single DNA-dependent RNA polymerase catalyses transcription of all types of RNA. (II) Sigma ( ) factor is required for the termination of transcription in prokaryotes. (III) In eukaryotes, there are at least three RNA polymerases in the nucleus. (IV) Rho ( ) factor transiently associates with RNA polymerase to initiate transcription. How many of the above st

Step-by-step solution

Statement (I) is correct as bacteria have a single DNA-dependent RNA polymerase that catalyses the transcription of mRNA, tRNA, and rRNA. Statement (II) is incorrect because the sigma ( ) factor is the initiation factor, not the termination factor. Statement (III) is correct as eukaryotes have a clear division of labour with at least three RNA polymerases (I, II, and III) in the nucleus (in addition to the RNA polymerase found in organelles). Statement (IV) is incorrect because the rho ( ) factor is the termination
