Which statement about sticky ends is wrong?

Answer and explanation

Correct answer: They are always blunt ends without overhangs

Sticky ends are produced when a restriction enzyme cuts DNA in a staggered manner, leaving a single-stranded overhang. This overhang can base-pair with a complementary DNA sequence, making DNA ligation easier. Ends with no overhang are called blunt ends, not sticky ends. Exam tip: overhang = sticky end; no overhang = blunt end.
