| Abstract: | Summary Tests that take into account the effects of gaps have been applied to 5S ribosomal RNA sequences from the bacteria,E. coli andP. fluorescens, and from KB carcinoma cells. The 5S RNAs from KB andP. fluorescens, when compared to that ofE. coli are shown to be more similar than random sequences of the same composition. Intrasequential analyses of 5S RNAs give some evidence for partial gene duplication or repetitive subsequences, but the proposed duplication of Brownlee, Sanger and Barrell (1968) is not supported by our data. |
