Comments P.921 bottom paragraph:"Since the water activity of very dilute solutions of different salts, as calculated from freezing point depression data, do differ slightly, the effect of very small changes in water activity on the buoyant densities of DNA was first determined by centrifuging DNA to equilibrium in metrizamide gradients which contained different concentrations of NaCl. Table 1 shows the changes observed in the buoyant density of native and denatured mouse DNA when the concentration of NaCl in the gradients was varied from 20 mM to 204 mM."
