Question

snRNAs are transcribed with the help of

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

Answer 1

The correct option is A RNA polymerase III

Introduction to RNA polymerase

• RNA polymerase enzyme helps in the initiation of synthesis and elongation of the RNA chain during transcription.
• It adds ribonucleotides complementary to the template strand of DNA starting from the initiation point and joins them by forming phosphodiester bonds.

RNA polymerase III

RNA polymerase III catalyses the transcription of tRNA , 5S rRNA and small nuclear RNA or snRNA.

Final answer:

(d) RNA polymerase III
