||P.507 left column 2nd paragraph: "The methods of measurement involved electron-microscopic examination of DNA in ultra-thin sections of mitochondria or isolation of mitochondrial DNA by differences in buoyant density or
chemical analyses of limited specificity (Bogenhagen and Clayton, 1974). As mt DNA only represents less than 1% of total cell DNA (primary source), contamination with
extramitochondrial DNA makes the results dubious."
