Effects of Decay of Incorporated H3-Thymidine on Bacteria

Abstract

The killing efficiency due to the decay of incorporated H3-thymidine in three mutants of E. coli strain 15: 15T-, 15T-L-, and 15T-U- has been determined. This efficiency is comparable to that previously determined by others for P32 decay. The killing efficiency has been determined as a function of H3-thymidine specific activity, storage media and storage temperature. We have observed a latent killing effect that causes lethality under certain conditions. The kinetics of latent killing have been examined at several temperatures. Finally, mutation production induced by H3-thymidine decays was shown to occur. The results are consistent with the idea that inactivation and mutations may be caused by a process in the nuclear transmutation that is not associated with β-particle ionization damage.
