A genome is an organism's complete set of DNA, including all of its genes. Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome-more than three billion DNA base pairs-is contained in all cells that have a nucleus. Developmental Genetics studies how the genes regulate developmental changes in behavior and influence scientific approaches in several fields. It highlights the interdisciplinary approach of developmental genetics with new revolutionary technologies and details how these advances have accelerated our understanding of the molecular genetic processes that regulates development. Chromosomes come in matching sets of two (or pairs) and there are hundreds-sometimes thousands-of genes in just one chromosome. The chromosomes and genes are made of DNA, which is short for deoxyribonucleic. Genes, Genomes, and Genomics, with chapters written by internationally renowned experts, provide an enormous reservoir of new information in the various theoretical and applied aspects of unravelling the secrets hidden in the genes of plants, animals and microorganisms. A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, act as instructions to make molecules called proteins. In humans, genes vary in size from a few hundred DNA bases to more than two million bases. Moreover, the book presents a thorough overview of a wide array of methodologies from classical genetics to modern genomics technologies.
