Observe a scientist describe the process used to extract DNA from a cell and to analyze it on a gene chip. [1:41]

Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Describe gel electrophoresis
Explain molecular and reproductive cloning
Describe biotechnology uses in medicine and agriculture

At DNA from the Beginning, choose from classical genetics, molecules of genetics, genetic organization and control. Each concept is explained through animation, an image gallery, video interviews, biographies and links.

Part of a site on genetics, this page explores DNA as a forensic science. Explains how and why DNA can be used to convict or acquit a criminal from wrongdoing using forensic DNA analysis. Teacher resources too.

Four steps is all it takes to get DNA out of a variety of living things. The requirements include a blender, meat tenderizer, isopropyl alcohol, and a test tube. Sources of DNA include but are not limited to split peas, strawberries, broccoli and chicken livers.
