Researchers have identified mutations in the coding region of the lacI gene that lead to a change in the structure of the lacI repressor protein. In these mutants the lacI protein’s allolactose binding pocket is now permanently in the ‘bound’ state. Explain fully what consequence, if any, this will have on the production of lacZ protein in the mutant E. coli cells.
