Abstract excerpt
DNA sequences of 103 spontaneous mutants and 102 X-ray-induced mutants of the lacZ transgene from spleen, liver, and brain of the MutaMouse were examined and compared to elucidate characteristics of radiation-induced mutations in vivo. The radiation-induced mutants were isolated from genomic DNA of each tissue collected at 3.5 days after 200 Gy of whole body irradiation. Base substitution was predominant (80% or...
