Experiment 2 The induction of mutations in Escherichia coli by ethyl methane sulfonate and in Salmonella typhimurium by Tn10 The purpose of this experiment was to identify and isolate ethyl methane sulfonate (EMS) mutagenized colonies of Escherichia coli (lac-) which could no longer use lactose as a carbon source and to isolate Tn10 mutagenized colonies of Salmonella typhimurium which were induced auxotrophs and identify independent mutations. Results Mutants observed in Escherichia coli: Control
