Phage T7 infects male (F-plasmid-carrying) Escherichia coli cells abortively, whereas the closely related phage T3 grows normally. The inability or ability of phage to replicate in male host cells depends on whether the right end of gene 1 (coding for the phage-specific RNA polymerase) consists of T7 or T3 DNA base sequences.
噬菌体T7会使雄性(携带F质粒的)大肠杆菌细胞流产性感染,而与之密切相关的噬菌体T3则能正常生长。噬菌体在雄性宿主细胞中能否复制取决于基因1的右端(编码噬菌体特异性RNA聚合酶)是由T7还是T3的DNA碱基序列组成。
