title: Molecular mechanism for genetic recombination.
abstract: Symmetry considerations of proteinnucleic acid interaction suggest the existence of an alternate branched configuration for DNA induced by binding specific structural proteins to symmetrically arranged polynucleotide base sequences. The concept that such sequences exist at the ends of genes or operons leads to a molecular model for genetic recombination in eukaryotic cells.
