启动子

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基因则排列为簇。裂解周期所需要基因则以三个启动子起以多顺反子转式表达。

But if the gene copy contains disabling typos or is missing pieces of the original, such as the promoter, it will become a pseudogene.

但果基因出（像是失启动子）或序列发生错误使基因损坏，它们就成了伪基因。
