In molecular genetics, the pairing of single-stranded DNA molecules that have complementary base sequences to form duplex molecules. Reannealing and annealing (q.v.) differ in that the DNA molecules in the first case are from the same source and in the second case from different sources. See Chronology, 1960, Doty et al.; Alu family, mouse satellite DNA, reassociation kinetics, repetitious genes.
