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

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 use DNA profiling and related biological concepts to solve two cases of elephant poaching.

Several questions are embedded within the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, which explores the genetics of lactase persistence and evolution of the trait in some human populations.

This interactive module explores the environmental factors and species involved in five major mass extinctions.

The added information provided at pause points within the animation How We Get Our Skin Color allows for a richer exploration of the topic of human skin structure and function.

Several questions are embedded within the short film The Day the Mesozoic Died, which tells the story of the scientific quest to explain one of the greatest, long-standing scientific mysteries: the sudden disappearance of the dinosaurs at the end of the Cretaceous period.

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

This tutorial describes how DNA microarrays called Virochips are designed to detect known viruses and discover new ones.

This tutorial explores how fat is digested, transported, stored, and used for energy.

This tutorial describes the various forms of “fat” — from a tissue, to a cell type, to a class of molecules.

This tutorial explains how scientists analyze and interpret the large data sets generated by DNA microarrays.
