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.
DNA is not soluble inethanol. The colder the ethanol, the less soluble the DNA will be in it. Thus make sure to keepthe ethanol in the freezer or on ice. Procedures/Activities Step: 1 Duration: 10 minutes Teacher may choose prior to class to prepare the DNA extraction buffer.he colder the ethanol, the less soluble the DNA will be in it.
