| Abstract: | Summary In the course of the present investigations, NG induced Mal mutants ofE. coli B were subjected to the following studies: 1. mutation rate for different genetical characters; 2. frequency of reversion to wild type; 3. classification of Mal UVs mutants formalA ormalB; 4. genetical analysis of themalB UVs mutants. It was found that approximately 40% of the Ma1 UVs mutants mapped atmalA and 60% atmalB.
