Amber mutants of the related phages T3 and T7 were isolated and tested for their ability to restore-as the wild type does-thymidine incorporation in ultraviolet (UV)-irradiated, UV-sensitive, nonpermissive host bacteria (Escherichia coli B(s-1)). Most amber mutants had this ability. However, in both T3 and T7, mutants unable to promote thymidine incorporation under these conditions were found and classified into two well-defined complementation groups: T3DO-A and T3DO-B, T7DO-A and T7DO-B… CONTINUE READING
