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, tRNA molecules are synthesized by RNA polymerase III, which is specialized for transcribing small RNA molecules, including 5S rRNA and tRNAs. RNA polymerase I transcribes most rRNA (except 5S rRNA), and RNA polymerase II synthesizes mRNA and some snRNAs. Ribosomes, on the other hand, are involved in translation and not RNA synthesis.
