[Structure of polylysine-DNA complexes].
By the methods of nuclease digestion and electron microscopy the complexes of poly-I-lysine with phage T2 DNA were studied. At micrococcal nuclease digestion of complexes polylysine--phage T2 DNA structures resistant to nuclease and containing fragments of DNA with lengths of about 300, 600, 1200 base pairs were revealed. On the electron micrographs structures superficially resembling nucleosomes were detected.
