· a phenol phase. Phenol is the denser of the two liquids so it sits on the bottom. The phases are then mixed thoroughly. This forces the phenol into the water layer where it forms an emulsion of droplets throughout. The proteins in the water phase are denatured and partition into the phenol, while the DNA stays in the water (Figure 1).
