Formation and branch migration of Holliday junctions mediated by eukaryotic recombinases

Article Abstract:

The role of the eukaryotic recombinases in the mediation of the formation and branch migration of the Holliday junctions (HJs) is discussed. HJs are found to be extremely important in homologous recombination and are widely used for the production of crossover recombinants.
