Abstract In HeLa cells, under conditions where normal semiconservative synthesis is suppressed by hydroxyurea, the excision repair process after irradiation by UV results in a small amount of incorporation of nucleotides into nonreplicated DNA. By labelling the cytosine moieties of these repair patches, and measuring the ratio between cytosine and 5-methylcytosine, we have found that the level of methylation of cytosine in repair patches five hours after UV-irradiation of the cells is about half of that observed in normal semiconservatively synthesized DNA.
