The DNA base composition, including the minor base content, of 26 strains of bacteria was determined. The studied bacteria are sources of widely used restriction endonucleases. Approximately 35% of the bacterial DNAs contained N4-methylcytosine, about 60% contained 5-methylcytosine, and about 90% had N6-methyladenine.
测定了26株细菌的DNA碱基组成，包括稀有碱基含量。所研究的细菌是广泛使用的限制性内切酶的来源。大约35%的细菌DNA含有N4-甲基胞嘧啶，约60%含有5-甲基胞嘧啶，约90%含有N6-甲基腺嘌呤。
