difference between DNA in nucleus and mitochondrian
â¢ Mitochondrial DNA is found inside the mitochondria while nuclear DNA is found inside the nucleus of a cell. â¢ One cell contains approximately 99.75% of nuclear DNA and 0.25% of mitochondrial DNA.â¢ The mutation rate of mitochondrial DNA is nearly twenty times faster than that of nuclear DNA.he uniqueness of mitochondrial DNA is that it is maternally inherited as a linked set of genes, passed on to progeny in the cytoplasm of the egg cell; thus no recombination between maternal and paternal genomes occurs.
