ANSWER: During the extraction of DNA (or nucleic acids in general), there is a lot of contaminating proteins present. These contaminants must be removed. Proteinase K, which is a broad spectrum serine protease, is used in many DNA extraction protocols to digest these contaminating proteins.Feb 19, 2013
