Abstract: | We have used glycerol to study the relationship between hydroxyl radicals, one of the primary radiolytic products, and the production of DNA double-strand breaks in selected E. coli strains. Our results suggest that when bacteria are irradiated at doses up to about 120 Gray, hydroxyl radicals produce DNA lesions, but not double-strand breaks. |
