Brock Biology of Microorganisms, 13th EdiEon. Bacteriophage lambda replicaEon (temperate phage) •  Phage Lambda’s genome is linear dsDNA with cohesive ends, a region of single- stranded complimentary DNA. •  The cohesive ends join, forming a circular molecule of dsDNA. •  The Lambda genome is integrated at a specific site in the bacterial chromosome: the a-λ site. The a- region in the phage genome is homologous to the a-λ site. The enzyme lambda integrase catalyzes integraEon of the phage genome at this site. The lambda integrase is encoded on the phage genome. Brock Biology of Microorga...
