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.

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.

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.

Living Together

This activity explores images of the bobtail squid, which serve as phenomena for learning about symbiosis and interspecies interactions.

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.

DNA Profiling Activity

This multipart activity is designed to give students a firm understanding of genetic profiling using short tandem repeats (STRs), which is a process used by forensics labs around the world.

CSI Wildlife

This interactive module allows students to use DNA profiling and related biological concepts to solve two cases of elephant poaching.

Metabarcoding

This video describes the technology of metabarcoding, which allows scientists to determine herbivore diets based on the sequences of plant DNA extracted from animal dung.
