Abstract
In a mating mixture of Hfr and F- bacteria the gene for alkaline phosphatase undergoes a transient derepression at the time of transfer. It is shown that this escape from repression occurs in the donor cells and is probably connected with the synchronous duplication of the transferred genome.
摘要
在高频重组（Hfr）菌和F-菌的混合交配中，碱性磷酸酶基因在转移时会经历短暂的去阻遏。结果表明，这种从阻遏中逃逸的现象发生在供体细胞中，并且可能与转移基因组的同步复制有关。
