CRISPR-Cas9 technology has revolutionized gene editing. Which of the following statements accurately describes its core principle and application in addressing genetic disorders?

Accepted Answer

B. It utilizes a guide RNA to direct a nuclease enzyme to specific DNA sequences, allowing precise cuts for gene inactivation or correction. — The correct answer is B.
