Given below are two statements:
Statement $I$ : Restriction endonucleases recognise specific sequence to cut DNA known as palindromic nucleotide sequence.
Statement $II$ : Restriction endonucleases cut the DNA strand a little away from the centre of the palindromic site.

Statement I : Restriction endonucleases do recognise unique sequences to cut the DNA. These sequences are arranged in the form of a palindrome. So, statement I is correct. Statement II : Restriction endonucleases cut the DNA strand a little away from the centre of the palindromic site. This helps generate sticky ends. So, statement II is correct. Option 4 is correct. Note: Statement II is correct as per NCERT but is not correct scientifically as a general statement for restriction endonucleases.
