| Abstract: | Summary In a phage T7-resistant and galactose-sensitive derivative of E. coli B/r trp- it has been possible to show that MFD for UV-induced mutations is specific for Trp+ reversions (mainly of an ochre suppressor-containing type) but is without effect on galactose-resistant or D-fucose-resistant (ara Cc) forward mutations. |
