It is necessary for the gene that codes for the repressor of lac operon to be near the structural genes.

Question

Quizplus · Accepted Answer

The gene that codes for the repressor of the lac operon, known as the lacI gene, does not need to be physically near the structural genes (lacZ, lacY, and lacA) of the lac operon to function. The lacI gene can be located elsewhere on the chromosome and still produce the repressor protein that regulates the lac operon by diffusing through the cytoplasm and binding to the operator region.
