Accessible and user-friendly, Cell Biology, 4th Edition, provides a strong foundation for students entering health care career paths as well as higher level research areas. Clear, readable text and high-quality, detailed illustrations help readers quickly grasp challenging content-all focusing on cellular processes without delving into molecular processes. Drs. Thomas D. Pollard, William C. Earnshaw, Jennifer Lippincott-Schwartz, and author/illustrator Dr. Graham Johnson have thoroughly updated this popular text to ensure its relevance for students in biology, biotechnology, medicine, and pathophysiology, covering key principles of cellular function and explaining how molecular defects lead to cellular dysfunction and cause human disease. Clear, readable explanations provide a concise story about how cells function at the molecular level.     An intuitive chapter flow starts with genome organization, gene expression, and RNA processing as a foundation for understanding every aspect of cellular function and physiology.  Brings cellular biology to life for students interested in medical science by explaining how mutations in genes can compromise virtually every cellular system and predispose to human disease. Knowledge of cell biology has led to new treatments for cancer, heart failure, cystic fibrosis, and many other diseases.  Unique illustrations with realistic proportions and relationships explain every cellular process including the assembly of SARS CoV-2, the structures attaching mitotic chromosomes to microtubules, the mechanism of DNA replication and how pumps, carriers and channels orchestrate physiological processes from synaptic transmission to cellular volume regulation.  Covers exciting breakthroughs such as SMC motor proteins actively organizing chromosomal DNA, TOR kinases regulating metabolism, new types of immunotherapy for cancer treatment, mechanisms regulating fast axonal transport and their relation to neurodegenerative diseases, how completion of DNA replication sets the time for cells to enter mitosis, how a cascade of signals specifies the site of cell division, and newly understood pathways of normal and pathological cell death.  Enhanced eBook version included with purchase. Your enhanced eBook allows you to access all of the text, figures, and references from the book on a variety of devices.
