A new type of tandem base lesion has been observed in d(CpGpTpA) X-irradiated in aqueous solution. The lesion is attributed to the formation of a covalent bond between the C8 carbon atom of guanine and the methyl carbon atom of thymine. This tandem base lesion is formed in the absence of oxygen. It is the main product produced by ionizing radiation under these conditions.
