Gene Function, contains the proceedings of the 12th Meeting of the Federation of European Biochemical Societies held in Dresden, Germany in 1978. The meeting provided a forum for discussing progress in the understanding of gene function and covered topics ranging from the functional organization of chromatin to principles of interactions and recognition models. The role of DNA sequence in the recognition of restriction endonucleases and modification enzymes is also examined, along with gene expression, RNA processing and modification, and isolation and synthesis of genes. Comprised of 49 chapters, this volume begins with an overview of what can be learned from the genetic analysis of the lac repressor, followed by a discussion on the topography of the interaction the lac repressor, RNA polymerase, and histones with DNA. The reader is then introduced to complementarity and recognition code between regulatory proteins and DNA; chromatin replication in vitro; and the cytoplasmic "petite" mutation in Saccharomyces cerevisiae. Subsequent chapters explore arc-like and helical arrangements of nucleosome cores; changes in gene expression during cellular differentiation; polyadenylation and processing of pre-messenger RNA; and the molecular biology of bacteriophages T3 and T7. This book will be of interest to geneticists, biochemists, and molecular biologists.
