    Which of the following techniques is used to cut DNA at specific sequences?

    A Polymerase chain reaction (PCR) Correct Answer Incorrect Answer
    B Gel electrophoresis Correct Answer Incorrect Answer
    C DNA cloning Correct Answer Incorrect Answer
    D Restriction enzymes Correct Answer Incorrect Answer

    Solution

    The technique used to cut DNA at specific sequences is called restriction enzyme cleavage or restriction endonuclease digestion. Restriction enzymes are proteins that recognize specific DNA sequences, known as recognition sites, and cleave the DNA at or near these sites.
