Abstract:
Hole attack: A theoretical one-electron oxidation of nucleic base molecules and their pairs by positron is proposed, based on the calculations for positron-attached neutral forms of species, adenine (A), thymine (T), guanine (G), cytosine (C), and their Watson-Crick base pairs (A-T and G-C). The results reveal that binding of a positron to neutral isolated nucleic base molecules is base-selective.
