Like eukaryotes, but unlike bacteria, they have introns in their transfer RNA, but like bacteria they have polycistronic operons (gene regulators).

像真核生像菌，转运RNA中含有内含子，还有菌具备多顺反子操纵子（调控子）。

The lac operon is an inducible operon, whereas the trp operon is a repressible operon.

乳糖操纵元是可诱导操纵元；色氨酸操纵元是可阻遏操纵元。
