This video segment from NOVA: "The Killer's Trail" investigates the potential for DNA evidence to solve murder cases, even those from the distant past.

This site from Ohio State University provides a good outline of the process of replicating DNA. The outline contains a numerous amount of embedded vocabulary links, illustrations of the process and also review questions and solutions.

Once the code was discovered, how could DNA be manipulated, what tools would be needed to make use of DNA. These are some questions answered in this interactive website.

In story form, this complete site examines what DNA is, the structure of DNA, genes, and replication. For clarity purposes, the text is supplemented with drawings.

On this site, students learn about DNA and genes in the science of biology including the deoxyribonucleic acid molecule, nucleotides, codons, and interesting facts.

The Canadian Centre for DNA Barcoding was started in 2003 by Dr. Paul Hebert. He came up with the idea of barcoding the DNA of all known species and creating a database to them. You can find a good explanation of what DNA barcoding is,...

This article describes a British project to store frozen samples of DNA from endangered species. The goal is to preserve genetic information, should a species go extinct.

Explains the Lost Colony DNA Project which is attempting to find genetic links between people living today and the lost colonists of Roanoke Island. Also provides a list of family names of colonists and of descendant families that may be...
