The genetics of bacteria and their viruses are fundamental to modern biology. Genetic investigations and manipulations of bacteria and bacteriophage have made vital contributions to our basic understanding of living cells and to the development of genetic engineering and biotechnology. Bacterial and Bacteriophage Genetics provides students with a comprehensive introduction to this rapidly advancing subject. This fourth edition has been extensively revised and reorganized to reflect advances in the field. All of the major topics in modern bacterial and bacteriophage genetics are presented, including: mutations and mutagenesis (including adaptive mutagenesis); genetics of lytic and temperate bacterial viruses; transduction; genetic transformation; conjugation and plasmids; regulatory systems; recombination and repair; probability analysis in bacterial genetic experiments; applied basic genetics; evolutionary genetics. This new edition includes a greater discussion of evolutionary issues and contains problem sets at the ends of each chapter to test students" understanding.
