Vedclass · Answer

(C) Restriction enzymes are primarily classified into $3$ main types based on their structure,cofactor requirements,and the nature of their target sequences: $1$. Type $I$ restriction enzymes: These are complex enzymes that require $ATP$,$Mg^{2+}$,and $S$-adenosylmethionine $(SAM)$ for their activity. They cleave $DNA$ at sites distant from their recognition sequence. $2$. Type $II$ restriction enzymes: These are the most commonly used enzymes in biotechnology. They require only $Mg^{2+}$ as a cofactor and cleave $DNA$ at or near specific recognition sequences. $3$. Type $III$ restriction enzymes: These enzymes require $ATP$ and $Mg^{2+}$ and cleave $DNA$ at a short distance from their recognition sequence. Therefore,there are $3$ types of restriction enzymes.

Column-$I$	Column-$II$
$P$. Restriction endonuclease	$I$. Synthesizes $DNA$ copies
$Q$. $DNA$ polymerase	$II$. Cleaves $DNA$ molecules
$R$. $DNA$ ligase	$III$. Joins $DNA$ molecules
