Keywords

Escherichia coli; Genes; Genetic Code; Lactose; Molecular Biology; Mutation

Main Points of the Paper

  • The regulatory gene, i, codes for a protein whereas the operator gene, o, probably does not

Materials and Methods Used

  • Parent Strain: Δlac su-/ FiSo+z+y+
    • iS- dominant over i+ and not inducible by lactose sz 43
  • 5 strains with suppressor mutations
    • su-
    • su+1
    • su+2
    • su+3
    • su+4
