Options

• (a) - (i), (b) - (ii), (c) - (iii)

• (a) - (iii), (b) - (ii), (c) - (i)

• (a) - (ii), (b) - (iii), (c) - (i)

• (a) - (i), (b) - (iii), (c) - (ii)

Answer 1

(a) - (i), (b) - (iii), (c) - (ii)

Explanation:

	Column-I		Column-II
(a)	RNA polymerase I	(i)	18s rRNA
(b)	RNA polymerase II	(iii)	hnRNA
(c)	RNA polymerase III	(ii)	SnRNAs

Enzymes called RNA polymerases convert DNA to RNA. Each of the three primary RNA polymerase types found in eukaryotes is in charge of the transcription of distinct RNA types:

RNA polymerase I: Transcribes the majority of ribosomal RNA (rRNA) genes, including the 18s rRNA.

RNA polymerase II: Transcribes certain small nuclear RNAs (snRNA), microRNAs, and messenger RNA (mRNA) precursors, also referred to as heterogeneous nuclear RNA (hnRNA).

RNA polymerase III: Transcribes short RNAs, including certain snRNAs, 5S rRNA, and transfer RNA (tRNA) genes.
