Diving Adaptations in Sea Nomads

This activity guides the analysis of a published scientific figure from a study that investigated physiological and genetic adaptations in the Bajau, a group of people who traditionally do freediving.

Sodium Channel Evolution in Electric Fish

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.

Pelvic Evolution in Sticklebacks

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.

“Fixing” Gene Expression

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.”

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.

Stalking the Genetic Basis of a Trait

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.

Central Dogma and Genetic Medicine

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.

HIV Reverse Transcription and AZT

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

HIV Protease Inhibitors

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

Zebrafish and Skin Color

In this activity, students explore how experimental work in zebrafish led to a better understanding of the role of the gene SLC24A5 in human skin color. The activity complements the film The Biology of Skin Color.

Interactive Assessment for Evolving Switches, Evolving Bodies

A number of interactive questions are embedded within the short film The Making of the Fittest: Evolving Switches, Evolving Bodies, which illustrates how mutations in gene regulatory regions can result in the evolution of major anatomical features.
