Molecular genetics of bacteriophage P22

The viruses of bacteria are undoubtedly the easiest living organisms to study and to understand at the molecular level. Throughout the past 25 years, the study of these organisms has yielded information and insights concerning the basic nature of life (especially the molecular nature of heredity) and thus nourished the science of molecular biology. Accordingly, inolecular biologists continued to lavish attention upon a chosen few bacteriophages, with the result that a handful of these organisms are by far
