Match List-$I$ with List-$II$.

List-$I$	List-$II$
$A$. Transformation	$I$. Restriction enzyme
$B$. Cloning site	$II$. Transfer $DNA$ to host bacteria
$C$. Selection	$III$. Replication
$D$. Ori	$IV$. Antibiotic

Choose the correct answer from the options given below:

Read the following statements carefully and select the correct option $:-$
$(A)$ Source of the restriction enzyme Hind $II$ is Haemophilus influenzae.
$(B)$ If any protein encoding gene is expressed in a heterologous host,it is called as recombinant protein.
$(C)$ Microinjection method for injecting foreign gene is used for animal cell.
$(D)$ $\text{DNA}$ primers are chemically synthesized oligonucleotides that are complementary to the regions of $\text{DNA}$ in $\text{PCR}$.
How many of the above statements are correct?

Consider the following statements:
$I.$ Recombinant $DNA$ technology,popularly known as genetic engineering,is a stream of biotechnology which deals with the manipulation of genetic material by man in vitro.
$II.$ $pBR322$ is the first artificial cloning vector developed in $1977$ by Bolivar and Rodriguez from $E. coli$ plasmid.
$III.$ Restriction enzymes belong to a class of enzymes called nucleases.
Which of the statements given above are correct?

Yeast has become important in genetic engineering because it:

Which of the following statements is not true?
$I.$ $DNA$, being a hydrophilic molecule, cannot pass through cell membranes.
$II.$ $Agrobacterium$ $tumefaciens$ delivers a piece of $DNA$ known as $'T-DNA'$ in the $Ti$ plasmid, which transforms normal plant cells into tumour cells to produce chemicals against pathogens.
$III.$ Retrovirus, adenovirus, and papillomavirus are also now used as cloning vectors in animals because of their ability to transform normal cells into cancerous cells.
$IV.$ In genetic engineering, $DNA$ from different sources are cut with the same restriction enzymes so that both $DNA$ fragments have the same kind of sticky ends.
Choose the correct option.

Identify the parts $A$ and $B$ from the given figure of the $pBR322$ cloning vector:
