Q153 / 180 · AIIMS 2018 (27 May) · Zoology

Find out the incorrect match.

  • A
    RNA polymerase II - $h n$ RNA
  • Correct answer
    B
    $\begin{aligned} & \text { RNA polymerase I - rRNA, } 5 \mathrm{~S} r \mathrm{RNA} \text {, } \\ & \text { snRNA } \\ & \end{aligned}$
  • C
    RNA polymerase III - $t$ RNA, snRNA
  • D
    RNA polymerase II $-m \mathrm{RNA}$

Solution

Three types of RNA polymerases have following functions : (i) RNA polymerase I transcribes $r$ RNAs (ii) RNA polymerase II transcribes $m$ RNA and $h n \mathrm{RNA}$ (iii) RNA polymerase III transcribes $t$ RNA, 5SrRNA and snRNA

Hence, the correct answer is option: 'B'.
