The given figure represents a transcription unit. Select the correct option from the following.
Coding strand $\quad\quad$ Promoter

Given below are the two statements.
Statement $I$: Only one strand in the transcription unit functions as a template and is called the antisense strand.
Statement $II$: The non-template strand of the transcription unit is called the sense strand.
In the light of the above statements,choose the correct answer from the options given below.

Transcription is most similar to which of the following processes?

Choose the correct statement.

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 $:$

Match the following columns:

Column-$I$	Column-$II$
$(a)$ Splicing	$(1)$ Contains only exons
$(b)$ Capping	$(2)$ Addition of adenylate residues
$(c)$ Tailing	$(3)$ Removal of introns
$(d)$ $mRNA$	$(4)$ Addition of methyl guanosine triphosphate
