To determine whether the fip gene of Escherichia coli, which is required for filamentous phage assembly, is required for cell viability, we replaced the chromosomal copy of the gene with an inactive copy introduced on a plasmid. We found that the fip gene is dispensable. The method we devised, which should be generally useful, was also tested with an inactivated rho gene. As expected, the rho gene is essential.
为了确定大肠杆菌中丝状噬菌体组装所需的fip基因是否为细胞生存力所必需,我们用质粒上引入的无活性拷贝替换了该基因的染色体拷贝。我们发现fip基因是可有可无的。我们设计的方法应具有普遍实用性,还用失活的rho基因进行了测试。正如预期的那样,rho基因是必不可少的。
