title: [Preservation of the beta-galactosidase activity in E. coli cells containing the recombinant pUC19 plasmid].
abstract: Two BglII fragments of pJC703 cosmid were inserted into the plasmid PUC19. E. coli cells containing the recombinant PUC19/A plasmid acquired rifampicin resistance due to inserted rpoB gene but still expressed the Lac+ phenotype.
