Abstract
The expression of the P22 late operon was measured while the activator of the late operon, the product of gene 23, was provided in cis or in trans. It was found that expression of the late operon, assayed from a late-gene-lacZ gene fusion, was reduced by more than twofold when the only functional copy of gene 23 was present in trans.
摘要
在顺式或反式提供晚期操纵子的激活因子（基因23的产物）的情况下，对P22晚期操纵子的表达进行了测定。结果发现，当基因23的唯一功能性拷贝存在于反式时，从晚期基因-lacZ基因融合体检测到的晚期操纵子的表达降低了两倍多。
