Which downstream application needs highly pure DNA?

Answer and explanation

Correct answer: PCR and restriction digestion

Highly pure DNA is required for enzymatic downstream applications such as PCR and restriction digestion. PCR depends on a DNA polymerase, primers, nucleotides, and suitable ions; substances such as phenol, ethanol, excess salts, proteins, or detergents can inhibit the polymerase or alter the reaction conditions. Restriction enzymes can likewise lose activity or cut inefficiently when inhibitors remain in the preparation. Therefore option A is correct because both named procedures use DNA as a precise biochemical substrate. The other options are not molecular biology applications and neither tests DNA purity nor uses DNA-dependent enzymes.
