Abstract
STUDIES of aqueous systems of intact deoxyribonucleoproteins1 showed that they were markedly unstable. Storage at 2°–5° C. for 24–36 hr. produced a substantial depolymerization of the deoxyribonucleic acid component. This is in marked contrast to the stability of dissociated nucleoproteins in 1.0 M sodium chloride. It was felt that this instability might be functionally significant in the mechanism of radiation effects on biological systems. Studies were therefore made of the effects of X-radiation on aqueous nucleoprotein gels.
