The final section of this chapter presents basic transcription regulatory mechanisms and the concepts of the Operon and regulon. Advanced regulatory topics are found in Chapter 14.

T4 Bacteriophage as a Model Genetic System,is to illustrate the basic nature of genetic processes using relatively simple genetic systems as examples. In Chapter 2, the distinction is made between phages that are always virulent and those that can temper their lytic response to form lysogens. Chapters 6 and 7 discuss the intemperate (i.e., v

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