Methyl guanosine triphosphate is added at the $5'$ end of $hn-RNA$ in a process of:

Capping is a process in which ............. .

$AGGTATCGCAT$ is a sequence from the coding strand of a gene. What will be the corresponding sequence of the transcribed $mRNA$?

Which factor$(s)$ participate in the process of transcription in prokaryotes?

Match Column-$I$ with Column-$II$ and select the correct answer from the options given below.

Column-$I$	Column-$II$
$i$. Cistron	$a$. Addition of methylated $GTP$ to $5'$-end of $hnRNA$.
$ii$. Exon	$b$. Non-coding sequences which are removed by splicing.
$iii$. Intron	$c$. Segment of $DNA$ coding for a polypeptide.
$iv$. Capping	$d$. Coding sequences which appear in processed $mRNA$.

For the given sequence of $DNA$,identify the complementary sequence of bases on its $mRNA$ from the options given below.
$DNA$ $3'-ATGCATGCATGC-5'$
