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.
The physical force of the DNA clumping together as it precipitates pulls more strands along with it as it rises into the alcohol. You can use a wooden stick or a straw to collect the DNA. If you want to save your DNA, you can transfer it to a small container filled with alcohol.
