Question

Quizplus · Accepted Answer

Sticky ends are the result of staggered overhang digestions of DNA by restriction enzymes. The enzyme cuts the DNA in a way that leaves single-stranded overhanging ends or "sticky ends." These overhangs can then base pair with complementary overhangs, which is important in the formation of recombinant DNA.
