NettetAbstract. In 1964, the geneticist Robin Holliday proposed a mechanism of DNA-strand exchange that attempted to explain gene-conversion events that occur during meiosis in fungi. His proposal marked the birthday of the now famous cross-stranded DNA structure, or Holliday junction. To understand the importance of the Holliday model we must look ... NettetGenetic recombination is the physical breakage, exchange, and rejoining of two DNA molecules. Homologous or general recombination can be mediated by several different pathways in bacteria. Each of these pathways requires the RecA protein to align the DNA molecules between regions of substantial DNA sequence identity.
