Organization of DNA replication from the genome to the individual replisome/replicon. A fluorescently labeled human HeLa Kyoto cell with a typical late S-phase replication pattern is presented in the top left corner (scale bar = 5 μm). Magnified super-resolution replication foci, with white circles representing individual replication sites displayed in the middle of the top row. A scheme of clustered DNA loops with active replication sites (white) is shown on the right. Starting point of DNA replication, the replication origin (ori), and the region replicated from a single origin displayed in the bottom row. Each replicon is replicated by two replication machineries (magenta), composed of various replication proteins, magnified in the bottom left corner.
