Vedclass · Answer

(D) In recombinant $DNA$ technology,vectors like plasmids and bacteriophages are used to carry foreign $DNA$ into host cells.$1$. Bacteriophages and plasmids have the ability to replicate within bacterial cells independently of the control of chromosomal $DNA$ (bacterial nucleoid).$2$. Bacteriophages have very high copy numbers per cell,which allows for the production of many copies of the inserted $DNA$.$3$. Plasmids also have varying copy numbers,typically ranging from $1-2$ to $15-100$ copies per cell.Therefore,all the given statements are correct.

Column-$I$	Column-$II$
$P$. Bacteria	$I$. Lysozyme
$Q$. Fungi	$II$. Cellulase
$R$. Plant cells	$III$. Chitinase
