Identify '$U$','$V$' and '$W$' in the given figure of $pBR322$.

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.

Which of the following pairs is $NOT$ correct?

Match the columns:

Column-$I$	Column-$II$
$(a)$ Ethidium Bromide	$(i)$ Agrobacterium
$(b)$ Ti plasmid	$(ii)$ Tetracycline
$(c)$ $PvuI$	$(iii)$ Gel electrophoresis
	$(iv)$ Ampicillin

Match the following columns:

Column $I$	Column $II$
$A$. Recombinant $DNA$	$1$. Sea weeds
$B$. Gel electrophoresis	$2$. $DNA$ staining
$C$. Ethidium bromide	$3$. Plasmid $DNA$ that has incorporated human $DNA$
$D$. Agarose	$4$. Process by which $DNA$ fragments are separated based on their size

The given figure shows the cloning vector $pBR322$. Identify the labels $A, B, C,$ and $D$ correctly.
