Abstract Deoxyuridine labeled in C-5 with a one-atom-tehered 6-memberedring mitroxide (DUTA) was incorporated into the oligomer d(T)7(DUTA)d(T)7 by either the phosphotriester or phosphoramidite method. While the EPR specific activity (AEPR) of the phosphotriester product concurs with EPR data of nucleic acids spinlabeled enzymatically, a lower AEPR is observed with the phosphoramidite product. The
