| Abstract: | The 5S rRNAs of Escherichia coli, Bacillus stearothermophilus, and B. subtilis were isolated and their molecular conformation examined. All three 5S rRNAs were similar with regard to nucleotide chain length, base composition and general configuration. Several major differences were apparent between the secondary and tertiary conformations of the 5S rRNA of E. coli and the genus Bacillus. Only minor differences were noted between those from the two Bacillus species. Each 5S rRNA species had a different 5′-terminal nucleotide: E. coli-U; B. stearothermophilus-C; B. subtilis-G. |
