The topic of this years' ~osbach Colloquium was DNA integration. We have tried to bring together experts from different fields of research who are studying natural processes by which DNA molecules from differ ent sources are linked. It has been known for a long time that such linkage occurs between the chromosomes of bacteriophages and plasmids on the one hand and the chromosome of the bacterial host on the other. This process has been especially well studied in bacteriophage A. Since it is controlled in a complicated way, we began with a lecture by M. ptashne on these regulatory processes. H. Nash described the inte gration of bacteriophage A into the bacterial chromosome. To put this site-specific process into perspective, G. Mosig lectured on genetic recombination in prokaryotes in general and K. Murray described the use of bacteriophage A as an artificial vector for genetic engineering. A different kind of bacteriophage integration is shown by bacteriophage Mu, which is much less specific in its choice of an integration site than A. The properties of this phage were described by P. van de Putte.
Progress in Nucleic Acid Research and Molecular Biology
Includes bibliographies.
- Controversial topic because many of the proposed solutions or policies may damage the economy in the short term in order to reap health benefits which will only become apparent several decades in the future - Each chapter is written by experts in the field throughout the world
In the summer of 1976 a successful workshop on nucleic acids and protein synthesis in plant systems was organised in Strasbourg by Jacques Weil and Lawrence Bogorad. The participants in the workshop, were, without exception, excited both by the quality of the work discussed and by the rapid progress being made in several areas of genomic analysis and expression in plants. It also became apparent that there was a need for an international assembly of this sort at regular intervals. These workshops not only encourage stim ulating discussion and constructive thinking but also result in increased collaboration and productive liaison between laboratories with common interests. Hence a ten-day adv...
With contributions by numerous experts
Diagnostic cytology has recently enjoyed increased attention and significance in modern research. Essential information on latest developments in methods and applications in cytology is provided by this book. Chapters review methodological advances, such as in cancer detection, and explore potential relationships to molecular biology. Also discussed are: viral infection, fundamentals of quantitative methods, and the revolutionary role of immunocytochemistry in diagnostic cell typing. The new insights offered by transmission and scanning electron microscopy into cellular structure and function are discussed, and the connections between cytology and histology are highlighted. Epidemiology in connection with cytology is incorporated in special reports. The current developments described here will become routine methods of the cytology of tomorrow.
