5-Bromouracil (5-BU) was shown to enhance reverse mutation rates when added to conidia of a rib-1 strain of Neurospora crassa previously irradiated with ultraviolet light. A comparison is presented between various incubation intervals in the presence and absence of 5-BU while varying the UV dose. An increase in mutation frequency ranging from 0.028 - 2.05 X… (More)
