title: Comparison of the mutagenic effects of 35S decay in Escherichia coli strains WP-2 and WP-2S.
abstract: Comparison was made of the lethal and mutagenic efficiency of 35S yields 35Cl transmutation of incorporated 35S in cells of Escherichia coli strain WP-2 and WP-2S (UV-sensitive). Bacteria were stored at minus 196 degrees. 35S yields 35Cl transmutation induced a higher lethal effect in strain WP-2 than in the UV-sensitive strain WP-2S. Reversions try yields try+ were induced with an approximately similar efficiency in both strains compared.
