If the desired fragment is not unique in a restriction digest, what is an appropriate strategy?

Answer and explanation

Correct answer: Choose alternative enzymes or use a gel-purification strategy that separates the desired fragment

A fragment is not unique when the same or a very similar-sized band can arise from more than one DNA segment. In that situation, a band at the expected size alone may not prove that the desired construct has been obtained. One solution is to select a different restriction enzyme or enzyme combination that creates a more distinctive pattern. Another is to separate fragments on a sufficiently resolved agarose gel, excise the correct band, and verify it with additional digestion, PCR, sequencing, or another suitable method. Option A is correct because it improves discrimination. Ignoring the ambiguity risks cloning the wrong fragment, while smelling an enzyme or converting DNA into protein has no diagnostic role.
