In this hands-on activity, students build a paper model to explore how CRISPR-Cas9 is used to edit genes.

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

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

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.

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

This activity can be used in conjunction with the short film The Double Helix. It introduces students to the classic experiment by Matthew Meselson and Franklin Stahl, which revealed that DNA replication follows the semiconservative model.

This interactive module shows how DNA sequences can be used to infer evolutionary relationships among organisms and represent them as phylogenetic trees.
