Composite Map of Phage Lambda Integrated into E. coli Genome

(A) The process of recombination of phage attP with E. coli attB shown in green.

(B) E. coli genome with lambda phage integrated and attL and attR recombined sites.

(C) Sequence of the E. coli attL site with core O site annotated. Extra bases to take for yeast cloning indicates bases surrounding the attachment site that are included in the phage genome in the YAC construct. Integrase binding sites denote sites where the integrase enzyme binds.

(D) Sequence of the attR site.
