Extracted DNA
Extracted DNA. Close-up of DNA (deoxyribonucleic acid) in its purified form. Normally, these fine wispy strands are tightly coiled around proteins in condensed genetic structures known as chromosomes. DNA contains sections, called genes, that encode each cell's structure, function and behaviour. Photographed at the AFM (French Muscular Dystrophy Association), Evry, France.
