Question

Match the RNA polymerase types in column I with that of the product they synthesize in column II.

Column I	Column II
a. RNA pol. I	i. Synthesizes mRNA and hnRNA
b. RNA pol. II	ii. Synthesizes tRNA , 5 srRNA, Sn RNA in nucleolus
c. RNA pol. III	iii. Synthesizes rRNA (28S, 18S) in nucleolus

• A. a- i, b – ii, c - iii
• B. a – ii, b – iii, c – i
• C. a – iii, b – i, c – ii
• D. a – iii, b – ii, c – i

Answer 1

The correct option is C a – iii, b – i, c – ii

RNA polymerase I synthesizes rRNA subunits 28S and 18S, in the nucleolus.

RNA polymerase II synthesizes mRNA and hnRNA, inside the nucleus.

RNA polymerase III synthesizes tRNA , 5 srRNA, Sn RNA in the nucleolus.
