title: Isolation and restriction mapping of plasmids containing ribosomal DNA sequences from the rrn B cistron of E. coli.
abstract: Recombinant plasmids containing the entire 16S RNA gene from the rrn B cistron of E. coli inserted in Col E1 and pBR322 plasmid vectors have been constructed. These plasmids have been mapped using several restriction endonucleases as well as by DNA-RNA hybridization. These maps reveal previously undetected restriction sites in the rrn B cistron and in Col E1 plasmid DNA.
