A study was made of the possibility of ribosomal RNA synthesis in kinetoplasts of two crithidian species--C. oncopelty and C. fasciculata. The RNA synthesized by isolated kinetoplasts in sucrose gradients was resolved into the following five fractions; 23S, 16S, 12S, 9S and 6--4S. Since pure kinetoplast ribosomes contain 23S and 16S RNA, a supposition was made that the first two transcripts might be ribosomal RNAs. It is suggested that the kinetoplast DNA contains genes for rRNAs and that the synthesis of these RNAs occurs in the kinetoplast.
对两种短膜虫属物种——康氏短膜虫和束状短膜虫动基体中核糖体RNA合成的可能性进行了研究。分离出的动基体在蔗糖梯度中合成的RNA被分离为以下五个组分：23S、16S、12S、9S和6 - 4S。由于纯动基体核糖体含有23S和16S RNA，因此推测前两个转录本可能是核糖体RNA。有人提出，动基体DNA含有rRNA的基因，并且这些RNA的合成发生在动基体中。
