One of the most important molecules relating to cancer is called p53. This Click and Learn explains the structure and function of the p53 protein as well as how the protein's activity is regulated. Learn why p53 is called the guardian of the genome and how interfering with its function can lead to cancer.
Find out how researchers identify genetic diseases and determine possible treatments.

Taxonomy groups species by common traits. Modern taxonomy emphasizes evolutionary relatedness. Explore some principles of taxonomy by sorting twenty shells by their morphological characteristics.
Whenever a pictorial index of shells appears, you can click on an image of a shell to open it in a separate window. There you can click and drag your mouse over the shell to rotate it for a more detailed examination. Additionally, you can use the small buttons in the lower right corner of the window to rotate the shell.
This interactive module introduces the anatomy of the immune system and walks through the timeline of a typical immune response.
The timeline includes the differences between the first time a pathogen is encountered versus subsequent infections, including an explanation of how vaccines work. Different tabs, videos, images, questions, and a detailed glossary of terms allow this resource to be explored at varying levels of depth depending on the class. Refer to the "Educator Resources" tab in the Click & Learn for implementation suggestions.
All living humans originated from populations of ancestors who migrated out of Africa less than 100,000 years ago. Learn how scientists have used genetic markers to trace the migration routes and origins of modern human populations.
Explore the human body like never before! With hundreds of interactive anatomy pictures and descriptions of thousands of objects in the body, InnerBody.com will help you discover what you want to know about human anatomy, right here at your fingertips.

Vibrio harveyi is a marine bacteria that emits light only at high population density. The bacterial bioluminescence is controlled by a system called quorum sensing. In this system, signaling molecules are secreted, and when they bind to cell surface receptors, they turn on many genes, including those that produce bioluminescence.
