Abstract
SEVERAL investigators1,2 have found that the viscosity of solutions of deoxyribonucleic acid is reduced by irradiation with ultra-violet light of 254 mµ. This change could be the result either of main-chain scission which reduces the length of the molecules or of an increase in flexibility which allows the molecule to take up a more coiled configuration and thereby reduces the volume occupied in solution, as measured by the radius of gyration.
