Figure 4.
The kinetics of appearance of BER and NER incision products derived from the 32P-internally labeled covalently closed circular plasmids containing S-Sp (A), and Gh (B) lesions and linearized plasmid containing S-Sp (C) lesions as a function of incubation time in the same HeLa cell extract. The results of three independent experiments and their standard deviations are shown.
