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.

Photosynthesis

This multipart animation series explores the process of photosynthesis and the structures that carry it out.

Cystic Fibrosis Mechanism and Treatment

This animation shows how mutations in an ion channel protein lead to the genetic disease cystic fibrosis. The animation also discusses how research on this protein has been used to develop treatments for the disease.

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.

Selective Breeding in Maize

This activity guides the analysis of a published scientific figure from the world’s longest-running controlled artificial selection study, in which scientists tested whether they could use selective breeding to change the protein concentration of maize (corn).

The Teosinte Hypothesis

In this activity, students further explore the short film Popped Secret: The Mysterious Origin of Corn, by working through the mathematical concepts behind George Beadle’s claim that teosinte is the wild ancestor of maize.

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.

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.
