Vedclass · Answer

(B) Statement $I$ is correct: The $lac$ operator is a specific $DNA$ sequence within the $lac$ operon that binds specifically to the $lac$ repressor protein to regulate gene expression.Statement $II$ is incorrect: In bacterial gene regulation,each operon typically possesses its own unique operator sequence and a corresponding specific repressor protein. This specificity ensures that the operon is only expressed under the appropriate environmental conditions.

Statement $I$: Lac operator is present only in $lac$-operon and it interacts specifically with $lac$-repressor only.
Statement $II$: Each operon does not have a specific operator and a specific repressor.
