Modeling the Structure of DNA

In this activity, students build a paper model of DNA and use their model to explore key structural features of the DNA double helix. This activity can be used to complement the short film The Double Helix.

Lizards in Hurricanes

This activity explores images of anole lizards subjected to strong winds, which serve as phenomena for learning about natural selection and the impacts of extreme climate events.

Lizards in the Cold

This activity guides the analysis of a published scientific figure from a study that investigated how anole lizards may adapt to extremely cold temperatures.

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.

Why Two Heads?

This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.

“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.”

Sleep Clears β-amyloid from the Brain

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.

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.

Viral DNA Integration

In this hands-on activity, students model how a double-stranded DNA copy of the HIV genome is integrated into the host cell DNA.

Cell Division and Cancer Risk

This activity guides the analysis of a published scientific figure from a study that investigated how random mutations during cell division can contribute to cancer.
