Which of the following pairs is $NOT$ correctly matched?

Match List-$I$ with List-$II$:

List-$I$	List-$II$
$A$. Monocistronic gene	$I$. Coding sequence
$B$. Polycistronic gene	$II$. Intervening sequence
$C$. Exons	$III$. Mostly prokaryotes
$D$. Introns	$IV$. Mostly eukaryotes

Read the following statements $:-$
$(i)$ Eukaryotic $\text{mRNA}$ is polycistronic whereas prokaryotic $\text{mRNA}$ is monocistronic.
$(ii)$ Prokaryotic $\text{mRNA}$ is cap-less and tail-less whereas eukaryotic $\text{mRNA}$ is with cap and tail.
$(iii)$ 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?

Match the following columns:

Column-$I$	Column-$II$
$(W)$ Griffith	$(1)$ $DNA$ is the genetic material
$(X)$ Avery,MacLeod	$(2)$ Semiconservative replication
$(Y)$ Meselson-Stahl	$(3)$ Transforming principle
$(Z)$ Hershey and Chase	$(4)$ Transformation inhibited by $DNase$
