    Abstract:
    The complexes of gene 5 protein (phage f1) with single-stranded and double-stranded polynucleotides were investigated by circular dichroism (CD). In our experiments the concentration of the protein varied accordingly to polynucleotide. A decrease of the CD amplitude for polynucleotide-protein complexes was shown in all the regions of wavelength studied. The data indicate that the protein is bounded to the polynucleotide. This protein bounds differently to double-stranded polynucleotides containing ribo-ribo, ribo-deoxyribo and deoxyribo-deoxyribo chains. This difference is explained by differences in the form of the secondary structure of polynucleotides, containing ribo-ribo, ribo-deoxyribo and deoxyribo-deoxyribo chains.
