Vedclass · Answer

(A) $1$. Restriction enzymes are a type of enzyme that cuts $DNA$ at specific sites. They belong to a larger class of enzymes known as nucleases.$2$. Nucleases are categorized into two types: exonucleases (which remove nucleotides from the ends of $DNA$) and endonucleases (which make cuts at specific positions within the $DNA$).$3$. Restriction endonucleases are a specific type of endonuclease that recognizes a specific palindromic nucleotide sequence in the $DNA$ and cuts the $DNA$ at that site.$4$. Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.

$A$: Restriction enzymes belong to a larger class of enzymes called nucleases.
$R$: Each restriction enzyme recognizes a specific palindromic nucleotide sequence in the $DNA$.
