This website offers interactive tutorials, videos and instructional activities designed to help students explore how researchers use bioinformatic tools and biological data to make new discoveries. Tutorials include DNA...

This animation from Cold Spring Harbor Laboratory's Dolan DNA Learning Center presents DNA arrays. The animation contains information on Pat Brown's discovery and the purpose of DNA arrays to study gene expression as...

The Using DNA Barcodes to Identify and Classify Living Things laboratory demonstrates several important concepts of modern biology. During the course of this laboratory, students will collect and analyze sequence data...

This animation demonstrates how DNA microarray experiments are performed. DNA chips are used to determine which genes are activated and which genes are repressed when two populations are compared. In this case, the...

The discovery of enzymes that could cut and paste DNA made genetic engineering possible. Restriction enzymes, found naturally in bacteria, can be used to cut DNA fragment at specific sequences, while another enzyme, DNA...
