Highly acceptable : DNA is a flexible medium with a range of conformational states. Thus, in investigations of the DNA‐mediated reductive electron transfer using a modified DNA duplex containing 5‐bromo‐2′‐deoxyuridine (red in picture) as the electron acceptor and pyren‐1‐yl‐2′‐deoxyuridine (blue) as the electron donor, a distribution of electron‐transfer rates has been observed.
