What is the benefit of making DNA aliquots?

Answer and explanation

Correct answer: To avoid repeated freeze-thaw cycles of the DNA sample

DNA is divided into small portions (aliquots) and stored in separate tubes. When needed, only one aliquot is thawed, preventing repeated freeze-thaw cycles of the main DNA stock and helping preserve DNA quality. Cutting DNA into fragments is done by restriction enzymes, not by aliquoting. Exam tip: remember that aliquoting is mainly used to protect sample stability and quality during storage.
