Mobilization and Reassembly of Genetic Information documents the proceedings of the Miami Winter Symposium, sponsored by the Department of Biochemistry, University of Miami School of Medicine, Miami, Florida, January 1970. This volume is the 17th in the "e;"e;Miami Winter Symposia"e;"e; series. Topics for the Miami Winter Symposia focus on areas of biochemistry in which recent progress offers new insights into the molecular basis of biological phenomena. The manuscripts presented by researchers at the symposium cover a wide range of topics including modified gene expressions induced by transposable elements; regulation of tn3 transposition and specificity of its insertion sites; the fusion of DNA molecules and genetic recombination; and control of cell type in yeast by genetic cassettes. Subsequent chapters include studies such as stable and unstable expression of genes in DNA transformed cells; transposable elements in the Drosophila genome; the genesis of avian retrovirus oncogenes; synthesis and processing of the mouse globin mRNA precursor; and type C virus expression in human placenta.
