  • Title: [Heterosis, macromolecular composition and several physico-chemical properties of the nucleolar-chromatic complex].
    Author: Shereshevskaia TsM, Krasnopol'skiĭ IuM, Verkhovskiĭ BA.
    Journal: Tsitol Genet; 1977; 11(3):217-21. PubMed ID: 910292.
    Abstract:
    The nucleolar-chromatin complex of the hybrids liver cells is shown to contain a larger amount of RNA and phospholipids. When teeated with 1.0 M NaCl nucleoproteins of hybrid organisms display greater dissociation. A large number of free loci was determined in the matrix when titrating nucleolar chromatin complex with actinomycin "D". The effect of heterosis might be connected with a specific physiochemical state of chromosome in hybrid organisms.
