Vedclass · Accepted Answer

Both Statement $I$ and Statement $II$ are correct

Vedclass · Answer

(A) Statement-$I$ is correct. The lac operator $(O)$ is a specific $DNA$ sequence in the lac operon that acts as a binding site for the lac repressor protein. This interaction is highly specific,ensuring that the operon is regulated only by its own repressor.Statement-$II$ is correct. Operons are gene regulatory units where each operon contains a unique operator sequence that is recognized by its corresponding specific repressor protein,ensuring precise control of gene expression.

Statement-$I$: Lac operator is present only in lac operon and it interacts specifically with lac-repressor only.
Statement-$II$: Each operon has its specific operator and specific repressor.
