Which of the following set of options is used in translation?
(1) hnRNA, tRNA, rRNA
(2) mRNA, tRNA, rRNA
(3) mRNA, tRNA, hnRNA
(4) hnRNA, rRNA, tRNA
(2) 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). mRNA, tRNA and rRNA are the functional RNAs which take part in translation.
