The book Gene Editing Principles and Applications is written by B.D. Singh & N.S. Shekhawat. Gene or genome editing is barely two decades old, but its impact is palpable in every discipline of biological sciences, especially basic and applied biomedical research. The present book is designed to provide the basic principles of gene editing as well as describe its realized and potential applications. The book targets biologists in general and geneticists, biomedical researchers, and plant breeders in particular. It is hoped that it will be useful to post-graduate students, research scholars, and research workers concerned with analyses of biological phenomena and the development of strains with novel and useful traits.
