Homologous recombination is an essential DNA repair mechanism in both prokaryotes and eukaryotes. It especially plays an important role in the repair of broken or stalled replication forks and is vital for proper chromosome segregation and immunoglobulin diversity. The main event in homologous recombination is the formation of a nucleoprotein filament by RecA-like proteins. Assembly of this filament is the rate-limiting step in recombination and it mediates subsequent stages of repair. Single-molecule experiments have given great insights into the physical mechanism and function of the nucleoprotein filament. In vivo, however, many recombination mediators are involved in the processes and various complex pathways are activated.
