Cell Division and Genetics explains what happens when cells divide. Cell division is the way in which organisms grow. Even when an organism is fully grown, some cells continue to divide to replace those that have become old or damaged. This book explores the complex relationship among chromosomes, genes, and DNA. It then examines the special form of cell division involved in reproduction, and how characteristics are passed on from one generation to another - so that a pig gives birth to piglets and not kittens! Each book features: charts and diagrams of important information, further reading and websites, extensive glossary and index. Book jacket.

Black & white print. Concepts of Biology is designed for the typical introductory biology course for nonmajors, covering standard scope and sequence requirements. The text includes interesting applications and conveys the major themes of biology, with content that is meaningful and easy to understand. The book is designed to demonstrate biology concepts and to promote scientific literacy.

Biology for AP® courses covers the scope and sequence requirements of a typical two-semester Advanced Placement® biology course. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology for AP® Courses was designed to meet and exceed the requirements of the College Board’s AP® Biology framework while allowing significant flexibility for instructors. Each section of the book includes an introduction based on the AP® curriculum and includes rich features that engage students in scientific practice and AP® test preparation; it also highlights careers and research opportunities in biological sciences.

Eggs of all animals contain mRNAs and proteins that are supplied to or deposited in the egg as it develops during oogenesis. These maternal gene products regulate all aspects of oocyte development, and an embryo fully relies on these maternal gene products for all aspects of its early development, including fertilization, transitions between meiotic and mitotic cell cycles, and activation of its own genome. Given the diverse processes required to produce a developmentally competent egg and embryo, it is not surprising that maternal gene products are not only essential for normal embryonic development but also for fertility. This review provides an overview of fundamental aspects of oocyte and early embryonic development and the interference and genetic approaches that have provided access to maternally regulated aspects of vertebrate development. Some of the pathways and molecules highlighted in this review, in particular, Bmps, Wnts, small GTPases, cytoskeletal components, and cell cycle regulators, are well known and are essential regulators of multiple aspects of animal development, including oogenesis, early embryogenesis, organogenesis, and reproductive fitness of the adult animal. Specific examples of developmental processes under maternal control and the essential proteins will be explored in each chapter, and where known conserved aspects or divergent roles for these maternal regulators of early vertebrate development will be discussed throughout this review.

Dr. Harris has played a major role in the development of this organism as a model system. Her previous version of the Chlamydomonas Sourcebook which published in 1989, has been a classic in the field and is considered required reading for anyone working with this organism. This latest edition has been expanded to include three volumes providing molecular techniques, analysis of the recently sequenced genome, and reviews of the current status of the diverse fields in which Chlamydomonas is used as a model organism. Methods for Chlamydomonas research and best practices for applications in research, including methods for culture, preservation of cultures, preparation of media, lists of inhibitors and other additives to culture media, are included. Additions to this volume also include help with common laboratory problems such as contamination, student demonstrations, and properties of particular strains and mutants. This volume is part of a 3-Volume Set (ISBN: 978-0-12-370873-1) and is also sold individually. - Expanded revision of gold standard reference - Includes latest advances in research, including completion of the genome - Provides broad perspective with studies in cell and molecular biology, genetics, plant physiology and related fields - Available as part of a 3-Volume Set or sold individually
