When is chain-of-sample record useful in restriction digestion?

Answer and explanation

Correct answer: While handling multiple DNA samples and clones at the same time

A is correct. During restriction digestion, handling several DNA samples, clones, or tubes together increases the chance of sample mix-ups or incorrect labelling. A chain-of-sample record documents the sample identity, source, label, and sequence of handling steps. Such a record can still be useful for one tube, but it is most important when multiple samples are being processed. Exam tip: Choose sample tracking or chain-of-custody procedures when the risk of mix-up is high.
