Answer: 3. Palindromic Nucleotide sequences

Restriction endonucleases recognise specific palindromic nucleotide sequences in DNA and cut at or near them. A palindrome reads the same on both strands in the 5'→3' direction, e.g. 5'-GAATTC-3' and 3'-CTTAAG-5'.

Primers, Okazaki fragments and poly(A) tails are not recognition sites for restriction enzymes.
