Quick Answer. Ethanol is used in DNA extraction to force the DNA to precipitate in a solution. In order to collect a DNA sample, cells are broken down through agitation, then mixed with water, salt and ethanol to create an aqueous solution.
Ethanol is less dense than water and will float on top. DNA is soluble in water, but salted DNA does not dissolve in ethanol and will form white clumps where the water and ethanol layers meet (Note 5). i Use a wooden stick or a straw (or a glass rod) to collect the DNA.thanol is less dense than water and will float on top.
