We are living in the middle of an information revolution that is changing all our lives. This revolution is more fundamental than the agricultural and industrial revolutions. The ability to sit in our homes and go shopping anywhere in the world, to browse the range of offerings, and to have items delivered to us is becoming commonplace. But this revolution also deals with information about ourselves, how we differ from others in minute detail, and how the cells that constitute our bodies are able to process the information that enables us to live our lives. This book represents a fragment of the biological information revolution as we struggle to gather the large number of facts that are required as a prerequisite to understanding life. We are not too far away from this understanding for simple life forms, perhaps ten years will suffice. It is fascinating to be living during this period. The authors of the various chapters have attempted to make some of the methodology accessible so that the techniques may be applied by others to enhance our knowledge.
