The 16S ribosomal RNA of the blue green alga Anacystis nidulans has been characterized in terms of the oligomers generated by digestion with T1 ribonuclease. A. nidulans by this criterion is definitely a procaryote; being no more distant from Bacilli or Enterics than the latter two are from one another. A. nidulans appears to be somewhat more closely related to the Bacilli than to the Enterics.
已根据用T1核糖核酸酶消化产生的寡聚体对蓝绿藻集胞藻6803的16S核糖体RNA进行了表征。根据这一标准,集胞藻6803肯定是一种原核生物;与芽孢杆菌或肠道菌的差异程度并不比后两者之间的差异更大。集胞藻6803与芽孢杆菌的亲缘关系似乎比与肠道菌的亲缘关系稍近一些。
