DNA being copied

Caption

Real image of DNA molecules being copied in human cells, visualized by immunofluorescence microscopy. The yellow arrows mark where replication begins, and the white arrows indicate the direction in which the molecule is being copied. The distance between the ends of the white arrows is about 100 thousandths of a millimeter (µM); it corresponds to 250,000 'letters' of DNA (bases). / Sara Rodríguez-Acebes. CNIO
