Bacteriophage lambda vectors, derived from lambda plac5 were constructed. Their genomes have only one EcoRI restriction site, located near the end of the beta-galactosidase gene. Recombinants, constructed in vitro, having a DNA fragment inserted in the EcoRI site, are lac- and can be easily recognized. Expression of such foreign genes is then under the control of the lac promoter.
