Lysis of mitochondria from sea urchin embryos with Triton X-100 led to a complete conversion of DNA-containing mitochondrial residues into protein-DNA complex with a density higher than 1.22 g/cm3 in sucrose solutions. This complex banded isopycnically in metrizamide gradients at a density of 1.26 g
