Answer is : (a) cut DNA at specific base sequences
Restriction endonuclease is an enzyme that cuts dsDNA into fragments at or near specific recognition sites (palindromic sequence) within the molecule known as restriction sites.
These enzymes are found in bacteria and archaea and provide a defence mechanism against invading viruses
