Answer
(A) - (IV), (B) - (III), (C) - (I), (D) - (II)
Explanation
Solution
In the lac operon, gene i codes for the repressor protein, gene a codes for transacetylase, gene y codes for permease, and gene z codes for β-galactosidase. This operon is a classic example of gene regulation in prokaryotes.
