title: Gamma-ray mutagenesis in bacteriophage T4.
abstract: 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.
