A direct confirmation of the specificity of mutation frequency decline for suppressor mutations.

C H Clarke.   

Abstract

In a phage T7-resistand 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.
