GAMMA-RAY MUTAGENESIS IN BACTERIOPHAGE T4

1 Department of Microbiology, University of Illinois, Urbana, Illinois 61801

137Cs-gamma irradiation of bacteriophage T4 induces large deletions plus a variety of types of point mutations. All mutations arise with single-hit kinetics, and all by a misrepair process. The estimated point mutation rate is 1.5 x 10-9 per locus per rad.
