If there are multiple restriction sites for an enzyme in a given molecule, digestion is carried out in many steps. The initial digestion should be? Correct Answer partial

If there are multiple restriction sites for an enzyme in a given molecule, the initial digestion would be partial. It is so because molecules cut on one site at an average.
