THYMIDINE is a specific precursor of deoxyribonucleic acid 1. The very low energy of tritium electrons permits precise localization on autoradiographs (within less than one micron on average) of ...

This process not only reduces the levels of dUTP but also provides dUMP, a precursor for the synthesis of thymidine triphosphate (dTTP), which is essential for DNA replication and repair.
