The choice of enzymes for an experiment depends on the specific requirements of your study. Generally, you would choose enzymes based on factors such as the DNA sequence you're working with, the desired outcome of the experiment, and the compatibility of the enzyme with your experimental setup. There's no fixed number of enzymes to choose per experiment, but selecting enzymes with appropriate recognition sites and desired cutting patterns is crucial for successful DNA manipulation
