Escherichia coli WP2 trpE65(ochre), when grown to stationary phase and plated on glucose salts medium, gave rise to slow growing tryptophan-independent mutants which formed increasing numbers of visible colonies from about day 6 onwards. These mutants were neither revertants at the ochre codon nor mutants at the tRNA suppressor loci normally found in this strain with logarithmic phase mutagenesis. The yield of mutants was not affected by the presence of the following alleles, umuC122, lexA102… CONTINUE READING
