  • Title: Comparative characterization of mitochondrial nucleoids and of nuclear chromatin of sea urchin embryos.
    Author: Sevaljević L, Rickwood D, Tomović M.
    Journal: Mol Cell Biochem; 1979 Jan 15; 23(1):53-61. PubMed ID: 423895.
    Abstract:
    Chromatin and mitochondrial nucleoids of sea urchin embryos were found to have different isopycnic densities in metrizamide gradients. The banding density of nucleoids was constant during development, while there appeared to be alterations in the density profiles of chromatin banded at low ionic strength.
