Assertion is correct, but Reason is incorrect.

Vedclass · Answer

(C) In eukaryotes, there are three distinct types of $RNA$ polymerases: $RNA$ polymerase $I$ (transcribes $rRNAs$), $RNA$ polymerase $II$ (transcribes $mRNA$ precursor), and $RNA$ polymerase $III$ (transcribes $tRNA$, $5s$ $rRNA$, and $snRNAs$). Thus, the Assertion is correct.Regarding the Reason, $RNA$ polymerase in prokaryotes (specifically the holoenzyme) consists of a core enzyme $(\alpha_2 \beta \beta' \omega)$ and a sigma $(\sigma)$ factor. The rho $(\rho)$ factor is a separate protein involved in the termination of transcription in prokaryotes, not a structural component of the $RNA$ polymerase enzyme itself. Therefore, the Reason is incorrect.

$A$ : $RNA$ polymerase is of three types in eukaryotes for the synthesis of all types of $RNAs$.
$R$ : $RNA$ polymerase consists of six types of polypeptides along with rho factor which is involved in termination of $RNA$ synthesis.
