In eukaryotes,$RNA$ polymerase $III$ catalyses the synthesis of

Which of the following is used as a substrate by $\text{RNA}$ polymerase and polymerises in a template-dependent fashion?

In the process of transcription in Eukaryotes,the $RNA$ polymerase $I$ transcribes

The portion of a gene that is transcribed but not translated is known as:

How many adenylate residues are added in the process of tailing?

Given below are two statements, one is labelled Assertion $(A)$ and the other is labelled as Reason $(R)$.
Assertion $(A) :$ In eukaryotes, primary transcripts $(hnRNA)$ contain both exons and introns, and introns are non-functional.
Reason $(R) :$ In bacteria, the $mRNA$ does not require any processing, and transcription and translation take place in the same compartment.
In the light of the above statements, choose the most appropriate answer from the options given below $:$
