Abstract excerpt
The ribosomal RNA multigene family in Escherichia coli comprises seven rrn operons of similar, but not identical, sequence. Four operons (rrnC, B, G, and E) contain genes in the 16S-23S intergenic spacer region (ISR) for tRNA(Glu-2) and three (rrnA, D, and H) contain genes for tRNA(Ile-1) and tRN...
