In Chapter 10, we studied the operon model. Note that, for the gal operon, the order of transcription of the genes in the operon is E-T-K. Suppose we have Fve different mutations in galT: gal-1, gal-2, gal-3, gal-4, and gal-5. The following table shows the ex- pression of galE and galK in mutants carrying each of these mutations: but not of upstream genes. Therefore, we would expect the insertion mutation to prevent the expression of the galK gene. Three mutations are in this category,
