polycistronic

All of the genes necessary for the lytic cycle are expressed in polycistronic transcripts from three promoters.

编码噬菌体结构成分的基因则排列为簇。裂解周期所需要的基因则启动起多顺反转录的形式表达。

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

像物而不像细菌，转运RNA中含有内含，还有细菌不具备的多顺反的操纵（基因的调控）。
