Gene Structure and Expression [Hardcover]

This third edition of a successful textbook is a concise description of the structure and function of genes.This concise guide to the structure and function of genes has been extensively updated, particularly in regard to recent advances in our understanding of DNA replication and transcription. It includes additional discussions of genes and the immune system and mitochondrial and chloroplast genomes.This concise guide to the structure and function of genes has been extensively updated, particularly in regard to recent advances in our understanding of DNA replication and transcription. It includes additional discussions of genes and the immune system and mitochondrial and chloroplast genomes.This new edition of a highly successful undergraduate text is a concise yet fully informative guide to the structure and function of genes. It describes DNA and how it replicates, how DNA is transcribed and translated into proteins, the organization of genes in prokaryotes and eukaryotes, the control of gene expression, and the role of retroviruses and oncogenes in cancer. There are additional discussions of gene families, genes and the immune systems, and mitochondrial and chloroplast genomes. The new edition has been extensively updated, particularly in regard to recent advances in our understanding of replication and transcription. Undergraduates studying genetics will benefit from this established text.Introduction to the third edition; Introduction to the second edition; Introduction to the first edition; List of abbreviations; 1.
