Bacteriophage DNA recombination. Molecular model showing DNA manipulation and recombination taking place at a Holliday junction with a bacteriophage enzyme. At left are strands of DNA (yellow and blue and pink and blue spirals, deoxyribonucleic acid). At right is the tetrameric (four subunits) structure of lambda-int, the integrase protein from a lambda bacteriophage. This complex forms a Holliday junction where the genetic material is excised or integrated into the host chromosome. Bacteriophages are viruses that infect bacteria. The lambda bacteriophage infects enterobacteria.
