PathwayStep2957 PathwayStep2956 Resolution of D-loop structures through Holliday junction intermediates Authored: Matthews, L, 2003-11-24 02:08:00 Following the synthesis of new DNA at resected 5' ends of the DSB, the heterologous DNA molecules may be ligated resulting in the formation of Holliday junctions. The Holliday structures are then cleaved resulting in reciprocal exchange of sequence between sister chromatids.
