Restriction endonucleases cut the DNA strand a little away from the centre of the palindromic site.
In the light of the above statements, choose the most appropriate answer from the options given below :

1 Both Statement A and Statement B are incorrect
2 Statement A is correct but Statement B is incorrect
3 Statement A is incorrect but Statement B is correct
4 Both Statement A and Statement B are correct
