Solution

The correct option is D DNA needs alcohol to be precipitated
DNA stays dissolved in aqueous solution after cell lysis and protease action. Salts are initially added to help precipitate DNA, following which ice-cold alcohol is added to the solution to accelerate the process. This technique is known as ‘salting out’.
