Question

tRNA is synthesized by:

• A. RNA polymerase I
• B. RNA polymerase II
• C. Ribosomes
• D. RNA polymerase III

Hint:

Focus on the specific RNA polymerases and their roles in eukaryotic transcription.

Answer 1

The Correct Option is D

In eukaryotes, RNA polymerase III synthesizes tRNA and other small RNA molecules, such as 5S rRNA. RNA polymerase I transcribes most rRNA, excluding 5S rRNA. RNA polymerase II is responsible for synthesizing mRNA and some snRNAs. Ribosomes facilitate translation and are not involved in RNA synthesis.
