Genetic research. Researcher setting up DNA (deoxyribonucleic acid) sequencing equipment. DNA sequencing determines the exact order of the four bases that make up genes, sections of DNA that encode how every cell in the body works. Sequencing DNA makes it possible to find the exact cause of a genetic disease. Photographed at the AFM (French Muscular Dystrophy Association), Evry, France.
