Given below are two statements: In the light of the above statements, choose the correct answer from the options given below:

  1. Statement I is correct but Statement II is incorrect
  2. Statement I is incorrect but Statement II is correct
  3. Both Statement I and Statement II are correct
  4. Both Statement I and Statement II are incorrect

Answer

(3) Both Statement I and Statement II are correct

Solution

Statement I: Besides the RNA polymerase of organelles, the eukaryotic nucleus has three RNA polymerases (I, II and III). Correct.

Statement II: RNA polymerase I transcribes rRNAs (28S, 18S, 5.8S), RNA polymerase II transcribes hnRNA (precursor of mRNA) and RNA polymerase III transcribes tRNA, 5S rRNA and snRNAs. Correct.

Answer: (3)
