Why is DNA sample concentration normalized before comparing restriction-digestion reactions?

Answer and explanation

Correct answer: To place an equal amount of DNA in the different reactions

Normalizing DNA concentration means adjusting samples so that the same DNA mass, or a deliberately chosen comparable amount, is used in each restriction-digestion reaction. If one tube receives much more DNA than another, its gel band may appear brighter even when digestion efficiency is identical. That difference could be mistaken for better cutting or a different construct. Equal DNA input makes comparisons of fragment pattern and approximate band intensity more meaningful. Therefore option A is correct. Normalization does not colour the enzyme, heat the gel, or cause protein synthesis, so B, C, and D are unrelated. Enzyme amount, buffer, incubation time, and DNA quality should also be controlled when comparing digestion results.
