Number of mutations required to evolve a new lactase function in Escherichia coli.
The frequency of mutation of the ebgAo allele to ebgA+ was compared with the frequency of mutation of strA+ to strA-. The observation that both spontaneous and ethyl methane sulfonate-induced mutations to ebgA+ occurred more frequently than mutations to strA- suggests that ebgA+ mutants arise as the...
