What is the role of salt, isopropanol and ethanol in DNA extraction?

WebDNA is less soluble in isopropanol so it precipitates faster even at low concentrations. The downside however is that salt will also precipitate in isopropanol. With ethanol, the DNA needs to be at a higher concentration to flocculate but the salt tends to stay soluble, even at colder temperatures.
