UV induced mutagenesis of bacteriophage T 7 was investigated by using a forward mutation system (host range system) and a back mutation system ( amber system). The results indicate a dependence of mutation of T 7 after UV irradiation only on the rec gene controlled functions of the bacterial host. The functions controlled by pol and uvr genes have no influence. Among other types of mutations UV irradiation leads to transitions from AT to GC.
