Question

This process occurs as I increases in Cohn’s equation. Ethanol and sodium acetate are added to induce this process, which is followed by a 70% ethanol wash, in a method to concentrate DNA. (15[1])This process occurs in a “hanging drop” or “sitting drop” in vapor diffusion. Ions high in the Hofmeister series (15[1])are more kosmotropic and better at inducing this process. It’s not denaturation, but this process can be induced for proteins by adjusting (15[1])the pH to the (*) isoelectric point or by adding ammonium sulfate. This process is performed by seeding a supersaturated protein solution to prepare samples (-5[1])for XRD. Adding salt to a silver chloride solution causes AgCl to undergo this process due to the common ion effect. For 10 points, name this process in which an insoluble compound settles as a solid out of solution. (10[1])■END■

ANSWER: precipitation [or crystallization; accept ethanol precipitation; accept salting out until “salt” is read; accept protein precipitation or DNA precipitation; accept answers indicating making crystals]
