Abstract excerpt
Mutations in several dna genes of Escherichia coli, when introduced into a strain with a lac fusion in the SOS gene sulA, resulted in formation of blue colonies on plates containing 5-bromo-4-chloro-3-indolyl-beta-D-galactoside (X-Gal). Unexpectedly, several lines of evidence indicated that the b...
