1·The repressor gene and its allele-a temperature sensitive mutant have been cloned from the defective prophage PBSX of Bacillus subtilis by means of PCR technique.

本研究利用聚合酶链式反应技术，成功地克隆了枯草芽孢杆菌缺陷型原噬菌体PBSX阻遏基因及其温度敏感型等位基因。

2·Church recalls seeing plasmid and gene sequences for the first time-penicillinase and insulin, the lac repressor and interferon.

Church回忆第一次见到了质粒和基因序列的情形-青霉素酶和胰岛素，阻遏物和干扰素。
