For decades this virus system has served--and continues to do so--to pioneer investigations on the molecular biology, biochemistry and genetics of mammalian cell systems. This three volume work presents an up-to-date account of recent basic research in one of the most important experimental systems for biochemical, cell biological, genetic, virological and epidemiological investigations in mammalian molecular biology. In this, the second of three volumes, the attention is turned to such topics as DNA replication, recombination and integration, and post-transcriptional control. The chapters have been written by an international group of leading experts in their respective fields of interest.
