DNA found in the mitochondrion of a cell differs in structure and is separate from the DNA found in the cell nucleus. Mitochondrial DNA, or mtDNA, exists as a circular loop of double-stranded DNA rather than the linear form found in nuclear DNA. However,

Unlike nuclear DNA, mtDNA is  inherited solely from the mother. (Mitochondria are predominantly from the mother’s egg and not from the father’s sperm.) Therefore, mtDNA sequences or orders of nucleotides generally remain constant over many generation
