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 explores how different animals — elephants, birds, and bats — have evolved distinct ways of using sound to communicate.

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

This interactive module explores the circulatory systems of major vertebrate groups to gain insights into their evolution.

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.

This model shows the structure of the protein BCR-ABL, which causes a type of cancer called chronic myeloid leukemia.

This model shows a mutated form of the cancer-causing protein BCR-ABL that is resistant to the drug Gleevec.

This model shows the structure of ATP, a molecule that provides energy for cellular processes, including protein phosphorylation.

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 describes the symbiosis between the Hawaiian bobtail squid and bioluminescent bacteria.
