Match the following:

Column $I$	Column $II$
$A$. $VNTR$	$p$. Largest gene
$B$. Introns and exons	$q$. $DNA$ fingerprinting
$C$. Dystrophin	$r$. Bulk $DNA$
$D$. Satellite	$s$. Splicing

For protein synthesis,$P$ can directly code,while each nucleotide of $Q$ has a $2'-OH$ group in its sugar. Identify $P$ and $Q$.
$\quad\quad P\quad Q$

$(iii)$ The precursor of prokaryotic $\text{mRNA}$ is $\text{hnRNA}$.
$(iv)$ In replication,only one of the strands acts as a template.
$(v)$ In eukaryotes,transcription occurs in the nucleus and translation in the cytoplasm.
Which of the above statements are correct?
