Which of the following is correctly matched?

Give differences between $PCR$ and plasmid.

Match the following items in List-$I$ with List-$II$:

List-$I$	List-$II$
$(a)$ Gel electrophoresis	$(1)$ Amplification of gene of interest
$(b)$ $PCR$	$(2)$ Separation of $DNA$ fragments
$(c)$ Bioreactor	$(3)$ Plasmid
$(d)$ Cloning vector	$(4)$ Production of desired product

Read the following statements and select the incorrect one:
$(I.)$ Disarmed Agrobacterium is used to deliver desirable gene into plant cell.
$(II.)$ In $\text{EcoRI}$,the letter '$R$' is derived from the name of species.
$(III.)$ Gene therapy is a part of modern biotechnology.
$(IV.)$ $\text{DNA}$ is a hydrophilic molecule,so it can easily pass through cell membrane.

Identify $X$ and $Y$ from the given figure of the cloning vector $pBR322$.

What does $P$ represent in the given figure?
