Which of the following is not a restriction endonuclease?

Eco $RI$

Hind $III$

$PS t\; I$

$DNAse$ $I4$

Solution

Restriction endonucleases are the enzymes, which cut a $DNA$ molecule within certain specific sites that have specific base sequence, eg., Hae $III$, Eco $RI$, Bam $II$, Hind $II$, Pst $I$, etc. $DNAse$$-I$ is not a restriction endonuclease enzyme. $DNA$ polymerase$-III$ synthesizes $DNA$, while $DNA$ polymerase$-I$ erases printer and fills gaps during $DNA$ replication.

Given below are two statements : one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$.
Assertion $(A)$ :
When a particular restriction enzyme cuts strand of DNA, overhanging stretches or sticky ends are formed.
Reason $(R)$:
Some restriction enzymes cut the strand of DNA a little away from the centre of palindromic site.
In the light of the above statements, choose the correct answer from the options given below :
