title: Comparison of mutagenic efficiency of decay of 32P incorporated in E. coli WP-2 and E. coli WP-2S cells.
abstract: 32P-labeled Escherichia coli WP-2 and Escherichia coli WP-2S cells were stored at minus 196 degrees. The lethal effect induced by 32P decay was equal in both strains. Lethal efficiency of 32P leads to 32P transmutation in DNA amounted to 0.046. Reversion try leads to try+ were induced with a ten times higher efficiency in UV--sensitive strain WP-2S, as compared with strain WP-2.
