Question

Which single enzyme in bacteria synthesizes all types of RNA (mRNA, tRNA, and rRNA)?

पर्याय

• RNA polymerase

• DNA polymerase

• Ribozyme

• Reverse transcriptase

Answer 1

A single RNA polymerase enzyme synthesizes all types of RNA in bacteria, including mRNA, tRNA, and rRNA. This is a key feature of bacterial transcription that distinguishes it from eukaryotic cells, which have three different RNA polymerases (RNA pol I, II, and III). The bacterial RNA polymerase recognizes different promoter elements to direct synthesis of the appropriate RNA type.
