Solution

The correct option is B Cutting of DNA at specific position only
Enzyme involve in the cutting of dsDNA molecule at palindromic sites are called Restriction endonucleases.
Examples are EcoR I, BamH I, Hind III, Pst I, Sal I.
So, the correct option is 'cutting of DNA at specific position only'.
