Coherent control of OH-free radicals interacting with the spin-triplet stateof a DNA molecule is investigated. A model Hamiltonian for molecular spinsinglet-triplet resonance is developed. We illustrate that the spin-tripletstate in DNA molecules can be efficiently populated, as the spin-injection ratecan be tuned to be orders of magnitudes greater than the decay rate due tosmall spin-orbit coupling in organic molecules. Owing to the nano-secondlife-time of OH free radicals, a non-equilibrium free energy barrier induced bythe injected spin triplet state that lasts approximately longer than one-microsecond in room temperature can efficiently block the initial Hydrogenabstraction and DNA damage. For a direct demonstration of the spin-blockadeeffect, a molecular simulation based on an {\em ab-initio} Car-Parrinellomolecular dynamics is deployed.
