Regulation of Gene Expression

 Which enzyme will be produced in a cell if there is a nonsense mutation in the lac Y gene?


A non-sense mutation creates stop codon. So, somewhere in the lac y gene a stop codon will be created. Therefore, lac z gene will be translated completely but not lac y and lac a gene. As a result, only β-galactosidase will be produced.
