The transfer range of phage genes was investigated at the single-cell level by using an in situ DNA amplification technique. After absorption of phages, a phage T4 gene was maintained in the genomes of non-plaque-forming bacteria at frequencies of 10(-2) gene copies per cell. The gene transfer decreased the mutation frequencies in nonhost recipients.
通过使用原位 DNA 扩增技术,在单细胞水平上研究了噬菌体基因的转移范围。在吸收噬菌体后,噬菌体 T4 基因以每个细胞 10(-2)个基因拷贝的频率保持在非噬菌斑形成细菌的基因组中。基因转移降低了非宿主受体的突变频率。
