A low level of recombination between homologous regions of plasmids and the host chromosome occurred during cell growth. The plasmids contained antibiotic resistance markers on the homologous regions which were only expressed when they were integrated into the chromosome. Such recombination took place in Rec+ rec-2 mutants but not in rec-1 mutants.
在细胞生长过程中,质粒与宿主染色体的同源区域之间发生了低水平的重组。这些质粒在同源区域含有抗生素抗性标记,只有当它们整合到染色体中时才会表达。这种重组发生在Rec⁺ rec⁻2突变体中,而在rec⁻1突变体中则不发生。
