To make it easier to cover CRISPR, a new section has been added to Concept 17.5 describing the CRISPR-Cas9 system, including Figure 17.28, вЂњGene editing using the CRISPRCas9 systemвЂќ (formerly Figure 20.14). In Concept 16.3, of Campbell Biology Book PDF, the text and Figure 16.23 have been extensively revised to reflect recent models of the structure and organization of interphase chromatin and how chromosomes condense during preparation for mitosis.Д¬hapter 17now describes the mutation responsible for the albino phenotype of the Asinara donkeys featured in the chapter-opening photo. Also, the вЂњFetal TestingвЂќ section has been updated to reflect current practices in obstetrics. In Chapter 14, of the Campbell Biology Book PDF 12th Edition the classic idea of a single gene determining hair or eye color, or even earlobe attachment, is discussed as an oversimplification. For example, a new Concept Check 13.2 question asks students about shoes as an analogy for chromosomes. This 3rd unit incorporates changes that help students grasp the more abstract concepts of genetics and their chromosomal and molecular underpinnings. In Chapter 12, the cell cycle figure (Figure 12.6) now includes cell images and labels describing the events of each phase. Chapter 10 also includes a discussion of the 2018 discovery of a new form of chlorophyll found in cyanobacteria that can carry out photosynthesis using far-red light. Chapter 9 includes new information on human brown fat usage, the role of fermentation during the production of chocolate, and recent research on the role of lactate in mammalian metabolism.Д¬hapter 10 begins with a new concept that puts photosynthesis into a big-picture ecological context. Chapter 7 begins with a new chapter-opening image showing neurotransmitter release during exocytosis. The Campbell Biology Book PDF 12th Edition provides the material more accessible, inviting, and exciting to students. In Chapter 5, the technique of cryo-electron microscopy is introduced, due to its increasing importance in the determination of molecular structure. Chapter 3 also has added coverage on the discovery of a large subsurface reservoir of liquid water on Mars and the first CO2 enhancement study done on an unconfined natural coral reef (both reported in 2018).Д¬hapter 4 now includes the discovery of carbon-based compounds on Mars reported by NASA in 2018. The opening photo for Chapter 3 features a ringed seal, a species endangered by the melting of Arctic sea ice due to climate change. In Unit 1, new content engages students in learning foundational chemistry. In addition, Unit 7 includes a new section on вЂњBiological Sex, Gender Identity, and Sexual Orientation in Human Sexuality,вЂќ which provides instructors and students with a thoughtful, clear, and current introduction to topics of tremendous relevance to biology, to student lives, and current public discourse and events. Content updates reflect rapid, ongoing changes in knowledge about climate change, genomics, gene-editing technology (CRISPR), evolutionary biology, microbiome-based therapies, and more. In place of an opening narrative, the first page of each chapter is arranged around three new elements which provide students with the specific tools and approaches needed to achieve the learning objectives of that chapter.ДЄs in each new edition of Campbell Biology Book PDF, the Twelfth Edition incorporates new content, summarized on pages xviiiвЂ“xx. In the 12th edition of the Campbell Biology Book PDF, The content is more visual, more interactive, and more engaging. They have also experienced textbook authors, having written Campbell Biology Book PDF 12th Edition in Focus in addition to Campbell Biology. The author teamвЂ™s contributions reflect their biological expertise as researchers and their teaching sensibilities gained from years of experience as instructors at diverse institutions.
