A model for the specific pairing of homologous double-stranded nucleic acid molecules during genetic recombination.
A model involving a specific pairing of homologous double-stranded nucleic acid molecules is applied to some parts of genetic recombination. The most original features of this application of the model relate to the initiation process, a part of which can be described by a highly compact and symmetrical structure. The model also provides a simple view of the formation of hybrid nucleic acid. The possibilities of detecting four-strand structures are briefly discussed.
