It is surprising, and even disappointing, that there have been very few meetings and published volumes resulting from these meetings that focus attention upon all of the groups of DNA tumor viruses. Historically, separate meetings were held each year for the adenovirus-SV40-polyoma researchers, the herpes- viruses, hepatitis B virus and the papillomaviruses. It was as if these four virus groups were four fields of study developing independently with a literature and culture of their own. When a virologist crossed the field from the adenovirus group to the herpesvirus or papillomaviruses, he...

Provided here is an easily accessible introduction to the mechanisms of DNA replication, regulation and the biochemistry of cell cycle control. An overview of this rapidly developing field is presented to orient the reader, followed by a series of contributions by leading researchers summarizing recent results on selected topics, such as protein phosporylation, tumor suppressor genes, and signal transduction in prokaryotic and eucaryotic systems. The reader will gain an overview of our current understanding of DNA replication and the cell cycle, and a selection of useful recent references for...

Genforschung, DNA, Gene und Genome, Genetik in Landwirtschaft und Medizin, in Erziehung und Psychologie - diese Begriffe sind nicht nur in der Fachwelt, sondern auch in den Feuilletons der Zeitungen, in Funk, Fernsehen und offentlichen Debatten des 21. Jahrhunderts allgegenwartig.

Dabei ist durchaus nicht jedem bekannt oder bewusst, dass die Genetik eine relativ junge Wissenschaft ist und erst Anfang des vorigen Jahrhunderts Gestalt annahm. Der zentrale Begriff des Gens erhielt dabei im Laufe der Jahrzehnte bis heute standig neue und andere Bedeutungen, oft befrachtet mit allerlei...
