"WebA Cas9 enzyme attaches to a particular DNA sequence when it is produced in a bacterial cell, and it subsequently cuts the DNA at that point. Compared to restriction enzymes, the Cas9 enzyme is far more effective in identifying and cleaving particular DNA sequences, and it can detect a much greater variety of sequences.
