The Recombination of Genetic Material aims to introduce the elementary properties of recombinational phenomena. Genetic recombination is a favorite research topic in biology due to its significance. In fact, a simple recombination event can have a profound effect and sometimes can mean the difference between the survival and the demise of an organism. Examples of this are provided in this book. This work also describes numerous recombination systems, mechanisms of the major types of recombination, and the macroscopic products of this biological process. Molecular analyses of recombination enzymes and substrates that have been identified or implicated are also shown. This book will be valuable as a reference material to those interested in this field of study.
