Removal of the inducer results in immediate cessation of enzyme synthesis. 除去诱导物就会立即终止酶的合成。
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. 在某些情况下，另外一种分子，即诱导物，可能与抑制子结合，减弱它与操纵子的结合作用，使基因去阻抑，转录可以进行。
