Abstract
A mutant strain of pneumococcus which fails to discriminate against low-efficiency markers during transformation by homospecific pneumococcal donor DNA retains the wild-type capacity to discriminate against heterospecific (streptococcal) donor DNA. We conclude that discrimination against heterospecific DNA must differ from that against low-efficiency markers by the kind or number of elements being recognized.
摘要
一种肺炎球菌突变株在同种肺炎球菌供体DNA转化过程中无法区分低效标记，但仍保留了区分异种（链球菌）供体DNA的野生型能力。我们得出结论，对异种DNA的区分与对低效标记的区分在被识别元件的种类或数量上必然存在差异。
