Figure 2.

The effect of Tg on the time for rejoining of an AP site (A) or a HAP1-SSB (B) when in different clustered sites following incubation with xrs5 nuclear extracts. The extent of accumulation of SSB+1 base during repair of an AP site (C) or a HAP1-SSB (D) when ddATP replaces dATP in the repair buffer. AP site control (con, filled circle: solid line) and AP/Tg at positions +1 (filled square: solid line), +5 (filled triangle: solid line), −1 (filled square: dashed line), −5 (filled triangle: dashed line). To assist the reader, lines have been drawn between the points to guide the eye only and do not represent fitted curves.
