Silencing, Heterochromatin and DNA Double Strand Break Repair

This book concerns the origin, evolution, distribution, and destiny of life in the universe. It discusses the transition from inert matter to cellular life and its evolution to fully developed intelligent beings, and also the possibility of life occurring elsewhere, particularly in other environments in our own and other solar systems. The theoretical framework of astrobiology may be probed with a forthcoming series of space missions, which at the time of writing are being planned for the next 10 to 15 years. Advanced extraterrestrial life can also be probed by means of radioastronomy in the well-established project of search for extraterrestrial intelligence. Astrobiology pays special attention to the robust growth in our capacity to search for microorganisms, as well as signals of extraterrestrial life, with recent significant technological progress in planetary science and radioastronomy. The progress of the main space agencies is highlighted.
