AIIMS 2018 Botany Protein Synthesis MCQ Question

In bacteria, protein synthesis is facilitated by a single type of RNA polymerase, which is responsible for transcribing all types of RNA, including mRNA, tRNA, and rRNA. This contrasts with eukaryotic cells, which utilize three distinct RNA polymerases for different RNA types. Option A is incorrect because, while all three types of RNA are involved in the process, the question specifically pertains to the number of RNA polymerases used. Option B is also incorrect as it misrepresents the bacterial system, which relies solely on one RNA polymerase for transcription.
