Question

In the following diagram of the lac operon, which is an operon for inducible enzymes, identify the components and enzymes.

• A. X - Repressor, Y - Inducer,$E_{1}$ - $\beta$ -galactosidase $E_{2}$ -Permease, $E_3 $ - Transacetylase
• B. X - Inducer, Y- Repressor, $E_{1} - \beta$-galactosidase $E_{2} -$ Permease, $E_{3}$ - Transacetylase
• C. X - Repressor, Y- Inducer, $E_{1} - \beta$ -galactosidase $E_{2} $- Transacetylase, E3 - Permease
• D. X - Repressor, Y - Inducer, $E_{1}$ - Permease, $E_{2}$ - Transacetylase, $E_{3} - \beta$-galactosidase

Answer 1

Answer: (A)

Correct answer is (a) X - Repressor, Y - Inducer,$E_{1}$ - $\beta$ -galactosidase $E_{2}$ -Permease, $E_3 $ - Transacetylase
