A Holliday junction is a junction between four strands of DNA. The structure is named after Robin Holliday, who proposed it in 1964 to account for a particular type of exchange of genetic information he observed in Ustilago maydis known as homologous recombination. Holliday junctions are highly conserved structures, from prokaryotes to mammals. Mo...

<molecular biology> A structure which occurs during homologous recombination between homologous chromosomes. While the two chromosomes are side by side, one strand of DNA on each chromosome is broken and then attached to the broken strand of DNA on the other chromosome. The crossover point, which is called the Holliday junction, is able to sl...
