The popular introduction to the genomic revolution for non-scientists—the revised and updated new edition Welcome to the Genome is an accessible, up-to-date introduction to genomics—the interdisciplinary field of biology focused on the structure, function, evolution, mapping, and editing of an organism's complete set of DNA. Written for non-experts, this user-friendly book explains how genomes are sequenced and explores the discoveries and challenges of this revolutionary technology. Genomics is a mixture of many fields, including not only biology, engineering, computer science, and mathematics, but also social sciences and humanities. This unique guide addresses both the science of genomics and the ethical, moral, and social questions that rise from the technology. There have been many exciting developments in genomics since this book's first publication. Accordingly, the second edition of Welcome to the Genome offers substantial new and updated content to reflect recent major advances in genome-level sequencing and analysis, and demonstrates the vast increase in biological knowledge over the past decade. New sections cover next-generation technologies such as Illumina and PacBio sequencing, while expanded chapters discuss controversial ethical and philosophical issues raised by genomic technology, such as direct-to-consumer genetic testing.
