Skin Color and Human Evolution

This activity guides the analysis of a published scientific figure from a study that investigated genetic factors contributing to skin color differences, particularly within African populations.

Monkey Social Status and Immune Response

This activity guides the analysis of a published scientific figure from a study on how social status affects the expression of genes involved in immune system processes.

HIV Receptors and Co-receptors

This demonstration models the first step of the HIV life cycle: the binding of HIV envelope proteins to receptors on human helper T cells.

Mapping Genes to Traits in Dogs Using SNPs

In this activity, students identify single nucleotide polymorphisms (SNPs) that are correlated with different traits in dogs to identify genes associated with those traits.

Cells of the Immune System

This tutorial provides an overview of the immune system, concentrating on the roles played by B and T lymphocytes, and on the antigen-presentation system.

Using DNA to Trace Human Migration

This tutorial describes how scientists determined that all living humans originated from populations in Africa. Some of these populations migrated out of Africa less than 100,000 years ago.

Immunology Virtual Lab

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