Frontispiece: Excess Electron Transfer through DNA Duplexes Comprising a Metal‐Mediated Base Pair

DNA‐mediated charge transfer represents a topical area of research. The influence of the site‐specific introduction of a metal ion into the base pair stack is a matter of current debate. In their communication on page 10244 ff., U. Karst, J. Müller et al. contribute to this debate by reporting an experimental study on excess electron transfer across a metal‐mediated base pair within a DNA double helix. To this end, LC/ICP‐MS was applied for the first time to quantify the electron‐transfer efficiency. The data suggest that a thymine–HgII–thymine base pair influences charge transfer in the same way as a thymine:thymine mispair does.
