Abstract excerpt
An extensive spectrum of ionizing radiation mutagenesis was determined by sequencing 318 137Cs gamma-radiation (anoxic)-induced episomal lacId mutations in Escherichia coli strain NR9102. The most commonly found radiation-induced mutations were base substitutions (44% transversions and 41% transitions). The radiation-induced spectrum consisted of: 23% G.C-->A.T, 18% A.T-->G.C, 17% G.C-->T.A, 14% G.C-->C.G, 8%...
