DNA-like RNAs from broad bean shoots, sea urchin embryos, T4-infected and non-infected Escherichia coli were fractionated by MAK column chromatography into three characteristic peaks. SDS-polyacrylamide gel electrophoresis and sucrose density gradient centrifugation of each RNA peak suggested that these peaks result from grouping of the RNAs by molecular weight. The three ranges for plant DNA-like RNA were different from those of phage-specific or bacterial mRNA. This may reflect some differences in the structures of DNA-like RNA between the organisms. Grouping of DNA-like RNA into three main size classes by an MAK column seems to be a general phenomenon occurring in a variety of organisms.
