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

This interactive module traces the evolutionary history of birds by comparing the bone structures of a chicken to those of other species.

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.

This interactive module explores the phases, checkpoints, and protein regulators of the cell cycle. The module also shows how mutations in genes that encode cell cycle regulators can lead to the development of cancer.

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 interactive module allows students to compare the morphological characteristics of seashells and construct an evolutionary tree.

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.

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