Vedclass · Answer

(B) The $lac$ operon consists of a regulatory gene ($i$ gene), a promoter $(p)$, an operator $(o)$, and three structural genes $(z, y, a)$.
The sequence of the $lac$ operon is: Regulatory gene $(i)$ - Promoter $(p)$ - Operator $(o)$ - Structural genes $(z, y, a)$.
Comparing this with the given table: $I$ corresponds to the Regulatory gene and $II$ corresponds to the Operator.
Therefore, the correct option is $B$.
