This activity guides the analysis of a published scientific figure from a study that investigated how gene duplication contributed to the evolution of electric fish.

This interactive module explores the biology of sex determination and development in humans, set against the backdrop of the different sex testing policies implemented throughout sports history.

This interactive module explores how CRISPR-Cas9 technology works and the many ways in which scientists are using it in their research.

This activity guides the analysis of a published scientific figure from a study that used SNP genotyping to identify the mutations that result in morphological differences in stickleback fish.

In this hands-on activity, students review the steps of eukaryotic gene expression and learn how this knowledge can be used to treat different genetic conditions. The activity reinforces concepts covered in the Click & Learn “Central Dogma and Genetic Medicine.”

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.

This activity supports the film Popped Secret: The Mysterious Origin of Corn. Students analyze data on the expression of the tb1 gene to explain how variations in this gene played a role in the evolution of corn.

This interactive module uses the central dogma as a model for exploring how modern molecular biology technologies can be used to treat different genetic conditions.

This activity analyzes a published scientific figure from a study that investigated the biological importance of sleep. In this study, scientists tested whether sleep plays a role in removing harmful substances from the brain.

This activity allows students to model how the anti-HIV drug AZT (azidothymidine) interferes with the process of viral replication.

This demonstration models how the HIV protease enzyme functions and how its activity is blocked by a class of anti-HIV drugs.

This interactive module explores biomes, climate, biodiversity, and human impacts around the globe and at different times.
