In this chapter descriptions of selected bacteriophages are presented to illustrate the high degree of genetic diversity available to the bacterial geneticist and to provide comparisons of these phages to each other and to T4. To facilitate these comparisons, the physical p

Instead of the customary unrestrained DNA replication and phage assembly, there is a temperate response in which the bacteriophage sets up housekeeping within the bacterial cell and maintain

Depending on which virus is involved, the donor cell DNA may or may not be associated with viral DNA inside the capsid of the bacteriophage. However, in

The molecules are then transported across the cell wall and cell membrane into the cytoplasm where recombination occurs. The process is distinct from

Nevertheless, Lederberg and Tatum, working at Yale University, chose to make another attempt using a common laboratory strain of bacteria, . K-12, as their experimental system. They also decided to test only a few isolates of t
