NEET Zoology Question (2026) — Solution

Step-by-step solution

In eukaryotes, there are three major types of RNA polymerases: RNA polymerase I transcribes rRNAs (28S, 18S, and 5.8S). RNA polymerase II transcribes the precursor of mRNA, which is known as heterogeneous nuclear RNA (hnRNA). RNA polymerase III is responsible for the transcription of tRNA, 5S rRNA, and snRNAs. Therefore, RNA polymerase II synthesizes precursor mRNA. Answer: RNA polymerase II
