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 investigation in mammalian molecular biology. In the first of the three volumes, we present an overview of adenovirus research. In the second volume, we turn our attention to such topics as DNA replication, recombination and integration and post-trans- criptional control. This, the third volume then looks at transformation and E1A, adenovirus genetics, pathogenesis and gene therapy.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.
