The response of populations of Bacillus subtilis to both native deoxyribonucleic acid (DNA) and denatured DNA was investigated at maximal competence and at various times during the development of compentency. The results indicate that competence for transformation with native and denatured DNA increases and decreases simultaneously. Competition occurs between native and single-stranded DNA during transformation, and the same cells in a population can be doubly transformed by DNA molecules of both configurations.
在最大感受态以及感受态形成过程中的不同时间点，研究了枯草芽孢杆菌群体对天然脱氧核糖核酸（DNA）和变性DNA的反应。结果表明，用天然DNA和变性DNA进行转化的感受态同时增加和降低。在转化过程中，天然DNA和单链DNA之间存在竞争，群体中的同一细胞可以被两种构型的DNA分子双重转化。
