Synopsis The complete set of instructions for making an organism is called its genome. It contains the master blueprint for all cellular structure and activities for the lifetime of the cell or organism. Found in every nucleus of a person’s many trillions of cells, the human genome consists of tightly coiled threads of deoxyribonucleic acid (DNA) and associated protein molecules, organised into structures called chromosomes. This book provides comprehensive and authentic information of the structural and functional aspects of the genetic materials. Major themes discussed are the molecular structure of genes and chromosomes; rearrangements of chromosomal DNA; organizing and packaging of DNA; organelle DNAs; mobile DNA; chromosomes in human genome and so on. For students, teachers, scientists, researchers and all others, interested in Genetics, this book will be a highly valuable references tool.
