Computer access is the only way to retrieve up-to-date nucleic acid and protein sequence and structure information. This book, edited by Martin Bishop, describes the available information and where to find it, and is essential reading for any researcher puzzled by the wealth of on-line data. The reader will be guided through the maze of URLs, sites and searches to reach information on: * DNA, RNA, protein sequence, and structure databases * Sequence comparison and alignmen * Phenotype, mutation and genetic linkage databases * Simple repetitive DNA sequences * Gene feature identification * Prediction of structure and function of proteins from sequence information The book includes a directory of URLs for easy reference and it will be invaluable to those starting a career in life sciences research and also for established researchers wishing to make full use of available resources.
