Why is a chain-of-custody type record useful for DNA samples?

Answer and explanation

Correct answer: For tracking the sample and ensuring accountability

A chain-of-custody record documents, in sequence, who handled or transferred a sample, when it was handled, and for what purpose. It therefore helps maintain sample identification, tracking, and accountability. Translation of DNA into protein is a cellular biological process, not a function of record keeping. Exam tip: Information about who handled a sample and when usually indicates chain of custody.
