Question

In eukaryotes, RNA polymerase III is responsible for synthesis of:

• A. 28$S$ rRNA, 18$S$ rRNA and 5.8$S$ rRNA
• B. $t$RNA, $hn$RNA, $r$RNA
• C. $t$RNA, 5$S$ rRNA, $sn$RNA
• D. $hn$RNA, $t$RNA, $r$RNA

Answer 1

The correct option is C $t$RNA, 5$S$ rRNA, $sn$RNA

In eukaryotic cells, RNA polymerase III (also called Pol III) transcribes DNA to synthesize ribosomal 5$S$ $r$RNA, $t$RNA and other small RNAs.
