The correct answer is: make cuts at specific positions within the DNA molecule
Restriction endonuclease recognizes a specific DNA base sequence (recognition sequence or recognition site, restriction sequence or restriction site) and cleaves both the strands of DNA at or near that site. The enzyme cuts the DNA, generating restriction fragments with overhanging ends or blunt ends.
