The data presented support the hypothesis that 16S, 23S, and 5S ribosomal RNAs of Escherichia coli are transcribed in vivo from transcriptional units consisting of single cistrons for these species arranged in the order 16S-23S-5S, with transcription beginning at the 16S end.
所呈现的数据支持这样一种假说,即大肠杆菌的16S、23S和5S核糖体RNA在体内是从转录单元转录而来的,这些转录单元由这些种类的单个顺反子组成,按16S - 23S - 5S的顺序排列,转录从16S端开始。
