A study on gene regulation using the lac operon

a study on gene regulation using the lac operon The lac operon encodes three proteins: β‐galactosidase (the product of the lacz gene), lactose permease (the product of the lacy gene), and lactose transacetylase (the product of the laca gene) the function of lac a is not known, but a mutation in either lac z or lac y means that the cell can't grow by using lactose as a sole carbon source.
