WebThe structural genes of the lacoperon (lacZ, lacY, and lacA) are transcribed efficiently to produce a polycistronic mRNA. The polycistronic mRNA is then translated to produce thousands of copies each of β-galactosidase, lactose permease, and galactoside transacetylase. Lactose is metabolized by the E. coli cell. WebSep 2, 2024 · In the lac operon, the structural genes are the lacZ, lacY and lacA genes encoding _-galactosidase, the permease, and the transacetylase, respectively. … oum meaning in chat brainly
