Teaching information, added to the original Student Edition text, includes margin notes with hints on lab procedures, additional art, and answers to in-text and end-of-chapter questions from the Student Edition. Also featured is a detailed Teaching Plan at the end of each lab with specific suggestions for organizing labs, including estimated time allotments for each part of the lab, and suggestions for encouraging independent thinking and collaborative discussions. The revised Sixth Edition includes a bioinformatics lab and references to relevant media on the companion website. Select tables can be found in Excel® format on the companion website, helping students to collect data directly on their computer, process this data using statistical tests, create graphs, and be ready to communicate their results in class discussions or reports.
