| These four case studies are interactivities based on actual scientific research projects carried out by leading teams in the field. Each case study takes the participant through a series of steps in a research project — just follow the step-by-step instructions to test a hypothesis or analyze data. The case studies provide an interactive experience that complements the video and text chapters and provides a window into the choices, challenges, compromises, and rewards associated with biological inquiry. |
| || ||The Genetics of Resistance to HIV Infection |
Can a person be truly resistant to HIV? Explore the phenomenon of "exposed unifected" individuals and learn more about the role of genes in disease resistance.
| || ||Evolution of Túngara Frog Mating Calls |
Use molecular information and observe female response patterns to learn about the mating calls of Physalaemus frogs, and how the calls have evolved over time.
| || ||Designing Cancer Drugs: |
Development of Gleevec
Follow the steps in the development of a cancer drug — from initial research on the targeted disease to the drug’s use in humans. Learn how drug design targets a disease by exploiting the structure of a protein that causes that disease.
| || ||Applied Genetic Modification |
Explore practical uses of genetic engineering techniques to generate a plant that produces a hepatitis B protein for potential vaccine use.
