Partial degradation of ribosomal RNAs (E. coli rich in purine nucleotides) by different ribonucleases gives rise to the appearance of several families of RNA-fragments which after separation on "Sephadex G 25" were analyzed for base ratio, size and biological activity. In the presence of DNA dependent DNA polymerase, RNA-fragments act as primers for in vitro replication of DNAs from numerous sources.
用不同的核糖核酸酶对核糖体RNA（富含嘌呤核苷酸的大肠杆菌）进行部分降解，会产生几个RNA片段家族。这些片段在“葡聚糖G 25”上分离后，对其碱基比例、大小和生物活性进行了分析。在依赖DNA的DNA聚合酶存在的情况下，RNA片段可作为来自多种来源的DNA进行体外复制的引物。
