The timecourse of UDS in cells exposed to UVC. (A) Images of EdU in nuclei (central cross-sections) of human fibroblasts at various time points following a UVC insult. Scale bar 5 μm; (B) The relative amounts of EdU incorporated within 0.25 h to 6 h after UVC exposure. Control refers to unirradiated cells. (C) The surface areas of central cross-sections of nuclei of cells, measured at different times after exposure to UVC (10 J/m²). The number of cells measure in each sample was 60–83.
