A group of related and closely linked structural genes, together with the operator gene that controls their expression are collectively called an operon . 一組相關(guān)的、緊密連鎖的結(jié)構(gòu)基因加上控制其表現(xiàn)的操縱基因,統(tǒng)稱(chēng)操縱子。
The regulator may code for a repressor protein that switches off an operator gene ( in bacteria ) 調(diào)解基因可能編碼一種抑制蛋白,能夠關(guān)閉一個(gè)操縱基因(在細(xì)菌中) 。
