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

The methods available for the isolation of DNA from various sources and in amounts varying from I kg to single intact molecules are reviewed. Emphasis has been placed on those methods which have been reported since 1960. The methods available for the separation of DNA from ribonucleic acids, polysae
72 mutants defective in the activity of the cell surface glycoprotein acid phosphatase were isolated and characterized. The mutants map in one genetic locus, phol. Many of them exhibit altered cell morphology. This characteristic cosegregates with acid phosphatase deficiency, implying that phol cont
