Bacteria of strain TK610 uvrA-6 his-4 umuC-36, when allowed to replicate their DNA for some hours after irradiation show induction of His+ mutations when subsequently exposed to visible light. It is suggested that base pair errors can be made opposite sites of pyrimidine dimers without involvement o

The photoreversibility of UV-induced mutations to Trp+ in strain Escherichia coli WP2 uvrA trp (unable to excise pyrimidine dimers) was lost at different rates during incubation in different media. In Casamino acids medium after a short initial lag, photoreversibility was lost over about one generat
The polC (= dnaE) temperature-sensitive DNA polymerase III mutation from Escherichia coli BT1026 has been transduced into E. coli WP2 (to give CM731) and WP2 uvr A (to give CM741). In excision-deficient CM741 UV-induced Trp+ mutations progressively lost their photoreversibility during post-irradiati
