Homology of ribosomal ribonucleic acid diverse bacterial species with Escherichia coli and Bacillus stearothermophilus.
Hybridization competition experiments were used to examine the ribosomal ribonucleic acid (rRNA) homologies of 22 bacteria and 3 higher organisms with Escherichia coli and Bacillus stearothermophilus. Although little or no homology was observed with the higher organisms, the bacteria showed a wide range of homologies. Organisms whose rRNA showed closer homology to E. coli rRNA showed less rRNA homology to B. stearothermophilus rRNA and vice versa.
