Site‐selective injection of a single electron into thymine (yellow) through the modified nucleoside 1(1→2) was used to examine the dependence of excess electron transfer in DNA on distance. The DNA was cleaved upon arrival of the electron at a thymine dimer (red). This assay showed that one electron can repair more than one UV‐induced lesion in DNA 3.
