Autoradiogram demonstrating DNA photodimer [DNA(3)] response to DNA photolyase as hybrid duplexes with PNA(4) and PNA(1). Samples containing photolyase (100 nM in enzyme assay buffer) are indicated as such by “enz.” Samples were irradiated at 350 nm in a Rayonet reactor at ca. 15–20°C, except for the sequencing lane labeled A+G, for the times indicated.
