Mutation frequency decline (MFD) in Escherichia coli was examined to demonstrate repair of targeting photoproducts during the post-UV incubation required in this process. Repair of mutation-targeting cyclobutane pyrimidine dimers (T <> C) was demonstrated when a correlation was established between t
Mutants able to grow in the presence of 1.2 mg/ml streptomycin were isolated from Escherichia coli WP2 after exposure to ultraviolet light (UV) or in the absence of any treatment (spontaneous), and from a umuC derivative after exposure to UV and delayed photoreversal. These mutants, characterized as
