A useful introduction from the Oak Ridge National Laboratory on the study of how genetics and behavior are linked. Many useful resource links are included.

Students learn how engineers apply their understanding of DNA to manipulate specific genes to produce desired traits, and how engineers have used this practice to address current problems facing humanity.

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.

This site from the Human Genome Project for the Oak Ridge National Laboratory is the index page for chapters which include an introduction to genes, the mapping sequence of genes, and the impact and future of the Human Genome Project.
