Some restriction endonucleases are capable of producing blunt ends; others can generate "sticky" ends.

Question

Quizplus · Accepted Answer

This statement is true. Some restriction endonucleases can create blunt ends, in which the cut occurs straight through the DNA double strand without leaving single-stranded overhangs. Other restriction endonucleases produce "sticky" ends, in which the cut occurs in a staggered fashion, leaving short, single-stranded overhangs or "sticky ends" that can base pair with complementary sticky ends created by the same or a different restriction endonuclease.
