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

This video case study explores the approaches scientists used to identify a mutation that causes retinitis pigmentosa (RP), a progressive disease that leads to blindness.

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 explores niche partitioning, a mechanism that enables similar species of animals to coexist.

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.

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.

A number of questions are embedded within the short film The Making of the Fittest: The Birth and Death of Genes, which illustrates how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.

This model shows the structure of the cancer drug Gleevec, which is used to treat chronic myeloid leukemia (CML).

This model shows the structure of the cancer drug dasatinib, which is used to treat chronic myeloid leukemia (CML).

This tutorial describes three examples of recent human adaptations: lactose tolerance, sickle cell disease, and bitter taste perception.
