Abstract
DNA from purified mitochondria of Drosophila melanogaster can be isolated as supercoiled molecules which when nicked have a contour length of 5.9 micron. Partial denaturation mapping shows regional heterogeneity of base composition with one early denaturing region, with a calculated GC content close to zero, extending over 20% of the genome. DNA isolated from unfertilized eggs shows nuclear and mitochondrial DNA in equal proportions; we found no evidence of other cytoplasmic species.Entities:
