title: Evidence for clustering of RNA polymerase and ribosomal protein genes in six species of Enterobacteria.
abstract: 32P-labelled DNA fragments from the E. coli beta operon were used as hybridisation probes for homologous DNA sequences in chromosomal digests of six species of Enterobacteria. In all species the hybridisation pattern suggested clustering of the genes comprising the beta operon.
