$(X)$ Avery,MacLeod	$(2)$ Semiconservative replication
$(Y)$ Meselson-Stahl	$(3)$ Transforming principle
$(Z)$ Hershey and Chase	$(4)$ Transformation inhibited by $DNase$

What does the figure shown above represent?

Given below are two statements.
Statement $I$: Heterocatalytic function of $DNA$ includes transcription and translation.
Statement $II$: $A$ unique feature of $DNA$ molecule which helps in its semiconservative duplication is the complementary nature of two strands.
In the light of the above statements,choose the correct answer from the options given below.

Match the following columns:

Column-$I$	Column-$II$
$(a)$ Exon	$(I)$ Non-coding sequence
