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

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

This tutorial describes methods used to detect when and where genes are expressed in cells and tissues.

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.
