摘要
Single-stranded DNA, whether homologous or not, stimulates purified Escherichia coli recA protein to unwind duplex DNA. This helps to explain how recA promotes a search for homology in genetic recombination. As oligodeoxynucleotides also stimulate unwinding, a common mechanism may relate the function of recA protein in recombination to other functions (SOS) induced by oligonucleotides. © 1979 Nature Publishing Group.
