The writing of this book is based on: 1. earlier experience writing textbooks for biology students with a university-level background in biology and biochemistry with many (>200) ?gures in these books (in Hungarian), 2. and on the necessity to present university lectures as power point presentations to catch the interest of s- dents. The author realizes that young readers who were grown up in an information society are relactant to read too much unless they have to take exams. Even then they prefer books which contain illustrations for a better understanding. In collaboration with colleagues, referees and members of the publishing staff an extensive set of photographs and illustrations were collected to provide a graphic follow-up to the text. Further aids for the student, instructor and the curious reader are provided by summaries, extensive sets of readings and references for each chapter, a glossary of the terms, list of abbreviations and a DVD with a red-blue eyeglass to visualize three dimensional chromatin structures. The reader could ask: Why another book on apoptosis? The answer to the question is related to the de?nition of the process. The term apoptosis has been introduced to describe typical morphological changes leading to controlled se- destruction of cells. The ?rst demonstrated biochemical feature of this type of cell death was internucleosomal fragmentation, which was occasionally preceded by the generation of large DNA fragments.
