Make genetics relevant with current high interest topics New - Expanded coverage of regulation of gene expression. Previously covered in a single chapter, regulation of gene expression is now divided into coverage of bacteria in Chapter 15 and coverage of eukaryotes in Chapter 16. Chapter 15 concludes with an introduction to CRISPR-Cas, and Chapter 16 includes thoughtful coverage of geneticists' important work in posttranscriptional regulation the past 15 years, including coverage of alternative splicing, mRNA stability and decay, and regulatory noncoding RNAs. New - Special Topic chapter on Genetic Testing guides students through the many contexts in which genetic testing is becoming prominent and explores many questions and ethical concerns related to its use. New - Special Topic chapter on Advances in Neurogenetics: The Study of Huntington Disease, explores how genetic analysis has informed scientists about the disease's causes, symptoms, and future treatment. All Special Topics chapters include a series of questions that help students review key ideas or facilitate personal contemplations and group discussions. Assessment questions for Special Topics in Modern Genetics Chapters are assignable in Mastering Genetics. Coverage of CRISPR-Cas is now integrated in multiple chapters.
The impact of genome editing is briefly introduced in Chapter 1. A basic overview of how the mechanism works in bacteria is covered in Chapter 15. Applications to biotechnology are explored in Chapter 17. Additionally, the use of CRISPR-Cas for genome editing for gene therapy and the production of genetically modified foods is covered in Special Topic Chapters ST3 and ST6. An increased emphasis on ethical considerations helps students think through ethical aspects of genetics-related issues. Essays that used to be known as Genetics, Technology, and Society have been replaced or revised as Genetics, Ethics, and Society . In addition, all chapters end with a Case Study , each of which raises ethical questions. Genetics, Ethics, and Society essays provide a synopsis of an ethical issue related to a current finding in genetics that impacts directly on society today.
It includes a section called Your Turn, which directs students to related resources of short readings and websites to support deeper investigation and discussion of the main topic of each essay. Case studies at the end of each chapter have been updated with new topics. Students can read and answer questions about a short scenario related to one of the chapter topics. The Case Studies link the coverage of formal genetic knowledge to everyday societal issues, and they include ethical considerations. Exploring Genomics boxes help students apply genetics to modern techniques such as genomics, bioinformatics, and proteomics. These boxes illustrate how genomic studies have an impact on every aspect of genetics. Exercises provide thoughtful questions and direct students to related online resources, allowing them to increase their awareness of genomics. Motivate students to develop and practice problem-solving skills Now Solve This Problems are integrated throughout each chapter to test student knowledge and build problem-solving skills while learning chapter content.
Exercises include a hint to guide students and a brief answer is provided in the answers appendix. One Now Solve This problem per chapter is linked to related end-of-chapter problems to make it easier for professors to assign similar problems for homework. How Do We Know? questions appear as the first entry in the Problems and Discussion Questions and ask students to identify the experimental basis underlying important concepts and conclusions-th.
