In this Click & Learn, students explore the process of digestion and how it connects to metabolism and cellular respiration. 

This interactive module explores the biology of sex determination and development in humans, set against the backdrop of the different sex testing policies implemented throughout sports history.

This interactive module explores how CRISPR-Cas9 technology works and the many ways in which scientists are using it in their research.

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.

This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.

This interactive module allows students to examine evidence from brain anatomy, tissue histology, and genetic studies to identify possible targets for the treatment of Alzheimer’s disease.

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

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

This tutorial describes the principles of DNA sequencing and sequence assembly, and shows how they apply to different sequencing techniques.

This interactive module explores the different gaits employed by animals and how the nervous system is able to switch between gaits.

This tutorial describes how neurons generate action potentials, and how scientists measure neuronal activity and record the firing of individual neurons.

This tutorial describes the structure and function of the p53 protein, how its activity is regulated in cells, and how mutant versions of p53 can lead to cancer.
