This introduction to microbiology has been illustrated with many applications to everyday life. More extensive coverage of molecular biology is offered than in most texts, enabling students to better understand microbiological principles and applications. The pronunciation of scientific terms is provided and key points appear throughout the text to focus attention on important concepts. Macromolecules, DNA synthesis, protein synthesis, regulation and microbial genetics are among the topics covered. Each chapter begins with a chapter outline so that the reader can see at a glance how the material is organized. Summary outlines at the end of each chapter aid review, and questions and topics for discussion are also included.
