Inside the Human Genomics Lab at Pennington Biomedical Research Center, Dr. Tuomo Rankinen points to a chip -- much like one you'd find in a computer -- that contains DNA samples. The chips are designed to read genetic markers, or DNA sequences, that determine things like blood type and eye color, and also risk for diseases like obesity.
