BCR-ABL: Protein Structure and Function

This tutorial describes the structure and function of the cancer-causing protein BCR-ABL. It also shows how drugs targeting this protein can help treat chronic myeloid leukemia (CML), a cancer of the white blood cells.

Lizard Evolution Virtual Lab

This interactive, modular lab explores the evolution of the anole lizards in the Caribbean through data collection and analysis.

Sorting Finch Species

This interactive module allows students to explore concepts related to speciation by identifying which birds belong to one of two finch species.

The Origin of Species: Lizards in an Evolutionary Tree

This film explores the adaptation of anole lizards (genus Anolis) to habitats common across the islands of the Caribbean. The anoles are excellent examples of adaptive radiation, convergent evolution, and speciation through reproductive isolation.

X Inactivation

This animation shows how X chromosomes are randomly switched off in most female mammals.

Ubiquitin and the Proteasome

This animation shows how proteins in the cell are tagged for disposal by ubiquitin and then degraded by the proteasome.

Immunology Virtual Lab

This interactive, modular lab explores how the ELISA method can be used to test blood samples for evidence of certain diseases.
