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

X - Repressor, Y - Inducer, $E_{1}$ - $β$ -galactosidase $E_{2}$ -Permease, $E_{3}$ - Transacetylase

X - Inducer, Y- Repressor, $E_{1} - β$ -galactosidase $E_{2} -$ Permease, $E_{3}$ - Transacetylase

X - Repressor, Y- Inducer, $E_{1} - β$ -galactosidase $E_{2}$ - Transacetylase, E3 - Permease

X - Repressor, Y - Inducer, $E_{1}$ - Permease, $E_{2}$ - Transacetylase, $E_{3} - β$ -galactosidase

Correct answer is (a) X - Repressor, Y - Inducer, $E_{1}$ - $β$ -galactosidase $E_{2}$ -Permease, $E_{3}$ - Transacetylase
