The content of this book centers on the processes that occur during growth of a single bacterial cell. Through the years, Dr. Cooper has made seminal contributions to our understanding of the bacterial cell cycle. This book is the result of his efforts to draw together and sift through almost all experimental data available in order to arrive at conclusions concerning the interconnectedness of division, DNA replication, cell growth, and the cell cycle. Readers may disagree with his sometimes strongly stated interpretations, but I encourage them not to be dissuaded because the book is a scholarly presentation of many important ideas. In fact, it is a major achievement dedicated to remembering and learning from the past.
