Intranuclear localization of UV-induced DNA repair in human VA13 cells.


We have investigated the intranuclear localization of DNA-repair synthesis in G1-phase VA13 human cells. Ultraviolet-irradiated cells were permitted to perform unscheduled DNA synthesis in 3H-thymidine (3H-TdR) and then extracted with nonionic detergent and 2 M NaCl to produce nucleoids in which residual nuclear matrix was surrounded by an extended halo of… (More)
