title: Comparison of the fine structure of mitochondrial DNA from Saccharomyces cerevisiae and S. carlsbergensis: electron microscopy of partially denatured molecules.
abstract: Denaturation-maps of mitochondrial DNA from Saccharomyces cerevisiae and S. carlsbergensis have been derived from electron microscopic observations of partially denatured complete circular molecules and large fragments of these circles. The mitochondrial DNA from the two species differ by 6% in total length, but seems from the maps to contain some regions of apparent close homology. The cleavage pattern of the two DNAs by the restriction endonuclease EcoRI is compared by gel electrophoresis.
