Abstract:
DNA is altered by the action of hydrogen peroxide, a ubiquitous body constituent. Formation of damaged species is established by changes in four characteristics of DNA: absorption in the ultraviolet, complexing with histone, adsorption by anion exchange resin and charcoal, binding of silver cations. Damaged species of DNA might lead to impaired function of the organism. Gamma globulin by complexing with DNA is a partial inhibitor of this attack by hydrogen peroxide.
