RESUMO

Physical mapping of the rRNA genes of Mycoplasma capricolum was done by digestion of the mycoplasmal DNA with EcoRI, PstI and BglII and hybridization with nick-translated probes consisting of defined portions of the rrnB ribosomal RNA operon of Escherichia coli. The results indicate that the rRNA genes in the chromosome of M. capricolum are arranged in two clusters, each organized in the order 5'-16S-23S-5S-3', resembling the order of the genes in the rrnB operon, with no large spacer regions separating the genes in each cluster.
