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 Likewise, can you extract DNA from an onion? Answer Chopping the onion allows its tissues to be broken up so that the meat ,...
