Question

Select the correct statement.
(a) RNA polymerase I transcribes rRNAs
(b) RNA polymerase II transcribes snRNA
(c) RNA polymerase lll transcribes hnRNA
(d) RNA polymerase II transcribes hnRNA

• A.
  b and c are correct
• B.
  a and d are correct
• C.
  a and c are correct.
• D.
  a and b are correct

Answer 1

The correct option is B

a and d are correct
Statement a

RNA polymerase I transcribes rRNAs (28S, 18S and 5.8S). Thus, statement ‘a’ is correct.

Statement d

RNA polymerase II catalyses the transcription of the precursor of functional mRNA, i.e, heterogeneous RNA or hnRNA. Thus, statement `d’ is correct.

Final answer:

a) a and d are correct
