Q163 / 180 · AIIMS 2015 · Zoology

Which of the following set of options is used in translation?

  • A
    hnRNA, $t$ RNA, rRNA
  • Correct answer
    B
    $m \mathrm{RNA}, t \mathrm{RNA}, r \mathrm{RNA}$
  • C
    $m$ RNA, $t$ RNA, hnRNA
  • D
    hnRNA, $r$ RNA, $t$ RNA

Solution

hnRNA (heterogeneous nuclear RNA) does not function until it undergoes processing. Post-transcriptional processing converts hnRNA into functional RNA, which then participates in translation (protein synthesis). $m$ RNA, $t$ RNA and $r$ RNA are the functional RNAs which take part in translation.

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