Sticky ends are fragments of DNA where one strand, after being cleaved by restriction enzymes, is left over hanging another strand. It is cleaved assymetrically and can leave a 5' or a 3' overhang. These overhangs are termed 'sticky' because they can easily bind to free nucleotides [1]. Restriction enzymes can also symmetrically cleave DNA strands to form blunt ends.

Some examples of Restriction endonucleases that cut to create 'sticky ends' are:

BamHI, BaI228I and EcoRI [2]
