Isolation and properties of DNA from eggs and gastrulae of Ascaris lumbricoides

, : Isolation and properties of DNA from eggs and gastrulae of Ascaris lumbricoides. Biochimica et Biophysica Acta 157: 209-212

Three types of DNA with different densities and G + C contents were demonstrated in the egg of Ascaris lumbricoides. It is assumed that the DNA with density 1.697 is nuclear DNA, the small fraction with density 1.693 is perhaps a satellite DNA and the DNA with density 1.685 is a cytoplasmic, perhaps mitochondrial DNA. The amount of the lower density DNA decreases during cell division in the early development of the eggs. The change in the proportion of the 2 main DNA components is in agreement with the change in the nuclear-cytoplasmic relationship in favour of nuclear DNA.
