DNA EXTRACTION FROM ONION - Iowa State University

An onion is used because it has a low starch content, which allows the DNA to be seen clearly. The salt shields the negative phosphate ends of DNA, which allows the ends to come closer so the DNA can precipitate out of a cold alcohol solution.

The filtration step (pouring the mixture through the strainer) allows for the collection of the DNA and other cellular substances. The precipitation step (pouring the cold alcohol down the side of the glass) allows the DNA to separate from other cellular substances. Finally, the DNA is removed from the solution by extraction with the toothpicks.
