Findings on the Electron‐Attachment‐Induced Abasic Site in a DNA Double Helix

One for the road: The potential-energy hyperface along the pathway of the formation of an abasic site (Pabasic) suggests that low-energy electrons (LEEs) might induce the formation of such a site at the 3′ end of a DNA double helix with the strand ended in a cytidine residue. Attachment of these LEEs to a DNA helix might significantly contribute to radiation-induced DNA damage. TS=transition state.
