UV light induces various photochemical reactions in DNA and is a known harm to our genetic material. One important reaction is the formation of charge‐transfer states between stacked nucleobases. In particular, guanine (dG) plays a major role as an electron donor, whose photophysical dynamics in short oligonucleotides have been investigated in detail in this study. The cover illustrates the charge‐transfer state in a guanine–adenosine dinucleotide, after absorption of UV light. More information can be found in the full paper by D. B. Bucher et al.
