Removal of the inducer results in immediate cessation of enzyme synthesis. 除去誘導物就會立即終止酶的合成。
In some cases another molecule, an inducer, may bind to the repressor, weakening its bonds with the operator and depressing the gene , allowing transcription to proceed. 在某些情況下，另外一種分子，即誘導物，可能與抑制子結合，減弱它與操縱子的結合作用，使基因去阻抑，轉錄可以進行。
