Biochemical Genetics discusses about the basic concept of biochemical genetics and the molecular genetics of the human. This book provides further information about the recombinant DNA technology and the prokaryotic molecular genetics. The plasticity of Genomes which is an alterable nature of the prokaryotic genomes has been described in one of the chapters in the book. The intent of this book is to describe the topics such as Medical Genetics and Epigenetics. Insights regarding the topic of molecular diagnostics have been provided to the readers with the help of this book, in order to understand the biochemical genetics in a better and broader way.
