To convert reaction times into reaction rates that include the search time t search for a substrate, we used the measured fraction of bound molecules: N bound / (N bound + N free) = t bound / (t bound + t search ). This gives the reaction rate per molecule: 1/ (t bound + t search ).

WebDNA repair, any of several mechanisms by which a cell maintains the integrity of its genetic code. DNA repair ensures the survival of a species by enabling parental DNA to be inherited as faithfully as possible by offspring. It also preserves the health of an individual.
