Abstract excerpt
In a previous study (Chen and Porter, 1988), we isolated spontaneous mutations in a test plasmid that had occurred under non-selective conditions and assigned them to 1 of 6 different categories or groups. The test plasmid, pRPZ126, is a pBR322 derivative containing the bacteriophage lambda immunity region with the cI857 allele so that plasmid-containing cells shifted to 42 degrees C survive only if the...
