Abstract

Nuclei from the Oömycete Achlya ambisexualis and rabbit kidney nuclei were digested with micrococcal nuclease and the resultant DNA fragments analyzed on slab gels. The average DNA repeat size was found to be 159 +/- 1.2 base pairs for Achlya and 199.8 +/- 3.7 base pairs for rabbit kidney. The presence of a DNA repeat size of 159 base pairs for Achlya extends the characterization of eukaryotic chromatins to this most primitive and perhaps unique microbe.

摘要

用微球菌核酸酶消化双性绵霉卵菌的细胞核和兔肾细胞核，并在平板凝胶上分析所得的DNA片段。发现绵霉的平均DNA重复片段大小为159±1.2个碱基对，兔肾的为199.8±3.7个碱基对。绵霉存在159个碱基对的DNA重复片段大小，这将真核染色质的特征扩展到了这种最原始且可能独特的微生物。
