The video and animation from the National Human Genome Research Institute (NHGRI) called "Our Molecular Selves" is a great introduction to the role our genome plays in shaping who we are. The NHGRI, which is part of the U.S. National Institutes of Health (NIH), developed the Human Genome Project in collaboration with the U.S. Department of Energy.
