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.
摘要
将pJC703黏粒的两个BglII片段插入质粒PUC19中。含有重组PUC19/A质粒的大肠杆菌细胞由于插入了rpoB基因而获得了利福平抗性，但仍表现出Lac+表型。
