This four-part animation series explores the biology of the virus SARS-CoV-2, which has caused a global pandemic of the disease COVID-19.

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 explores the diversity of viruses based on structure, genome type, host range, transmission mechanism, replication cycles, and vaccine availability.

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

This tutorial introduces students to vector-borne disease with a focus on dengue fever, which is transmitted by mosquitoes. Students also learn about strategies designed to stop the spread of disease by interfering with the mosquito life cycle.

This tutorial explores the effects of West Nile virus infection on different organisms and describes how the virus has spread throughout the United States since 1999.

This tutorial describes the role of telomeres, the ends of eukaryotic chromosomes, in DNA replication and cell division.
