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则排列为簇。裂解周期所基则以三个启动子起以多顺反子转录形式表达。

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

但果基出现短缺（像是缺失启动子）或序列发生错误使基，它们就成了伪基。
