Abstract
DNA-DNA hybridization was used to demonstrate that the substituted DNA in the bacteriophage λrecE (formerly called λ reverse) is homologous to DNA at the rac locus in Escherichia coli. Strains that are rac - do not contain appreciable amounts of this DNA, and it is lost from a rac + episome (F′ 123) after transmission to a rac - recipient. This is consistent with the proposal that the rac locus contains a cryptic prophage (Low, 1973).This publication has 30 references indexed in Scilit:
