IMPORTANT AND MEANINGFUL APPLICATIONS
Each chapter now opens with a real-world story that makes the material relevant for students. For example, the story of Nancy Wexler and her personal interest in establishing the heritability of Huntington’s Disease introduces a broader question introductory students will want to answer: what is the basis for the inheritance of disease? Each chapter-opening story is revisited toward the end of the chapter in light of the principles that have been covered.

THE LATEST TOOLS
Exploring Genomes: Web-Based Bioinformatics Tutorials introduce your students to the many genomic databases now central to genetics research today. Ten interactive tutorials teach students to use the vast genomic resources of the National Center for Biotechnology Information Web site. As a basis for these tutorials, the author, Paul Young from Queens University, draws upon relevant stories in the textbook, showing students how to use these bioinformatic resources as well as to see their potential for application in modern genetic analyses. Bioinformatics tutorials:
• An introduction to Genomic Databases
• Learning to use Entrez
• Learning to use BLAST
• Using BLAST to Compare Nucleic Acid Sequences
• Learning to use PubMed
• OMIM and Huntington Disease
• Finding Conserved Domains
• Determining Protein Strucutre
• Exploring the Cancer Anatomy Project
• Measuring Phylogenetic Distance.

NEW WAYS OF SEEING
• New! A Chapter Overview Illustration opens every chapter and serves as clear visual road map for the entire chapter.
• The visually stunning illustration program has been thoroughly expanded, updated, and revised. Over sixty new cutting-edge figures have been added. Each of the remaining illustrations has been carefully edited to ensure that it conveys its message clearly. In addition, the colors of the figures have been enhanced so the images are more vibrant and, thus, will project better during lecture hall presentation.
• New! Step-Through and Continuous Play FLASH Animations. These 45 animations were authored by Tony Griffiths with BioStudio Visual Communications. Each figure in the text that is accompanied by an animation is indicated by an icon for ready reference. These animations are also available on a student CDROM.

CLEARER EXPLANATIONS
The Second Edition fleshes out explanations, providing additional background information where necessary and adding new pedagogical diagrams to explain more complex processes, such as DNA replication. While still focused on the essential principles, these enhanced explanations will make the material more accessible to students.

AS ALWAYS, MORE INNOVATIONS FOR TEACHING PROBLEM-SOLVING
• New! Interactive "Unpacking the Problem" Authored by Craig Berezowsky in coordination with Tony Griffiths, both of the University of British Columbia.
• "Unpacking the Problem" exercises in the text use a series of questions to take students through the thought processes needed to solve a complex problem step by step. The new web-based, interactive versions of Unpacking the Problem features immediate feedback and grading functions. These are indicated with an icon next to one of the problems at the end of each chapter.

• The end-of-chapter problem sets are now divided into a group of Basic Problems followed by a group of Challenging Problems.

• Each chapter now includes several additional Basic Problems, giving students ample opportunity to practice the fundamentals of the chapter and thus gain confidence in their ability to apply principles. These additional practice problems will better prepare students for solving Challenging Problems later.

• Additional Pattern Recognition Problems help students recognize hereditary patterns in data, a key skill in genetic analysis.

• Greater Contrasting Color Palette in the Art Program makes it easier to identify the mechanics of each image.
