Vedclass · Answer

(C) Restriction enzymes are a class of enzymes that cut $DNA$ at specific sites. They are naturally found in bacteria,where they serve as a defense mechanism against invading viruses (bacteriophages) by cutting the viral $DNA$. They are not isolated from the bacteriophages themselves. Therefore,the statement that they are isolated from bacteriophages is incorrect. Restriction enzymes recognize specific palindromic sequences and act as endonucleases to produce sticky or blunt ends.
