There are several steps that need to be carried out when isolating mitochondrial DNA from tissue sample: 1) Tissue homogenization. Tissue homogenization represents the first step in the mitochondrial DNA (mtDNA) isolation workflow when starting with tissues e.g., muscle, heart, liver, brain, or kidney. To obtain sufficient amount of mtDNA for downstream analysis sufficient amount of mitochondria need to be prepared.
Mitochondrial DNA. Mitochondrial is passed from mother to child. Since only females pass on their mtDNA, testing the mtDNA tells about the mother, to her mother, and so on along the direct maternal line. Both males and females receive mtDNA from their mothers, so both men and women can test their mtDNA. While mutations occur in mitochondrial DNA, the rate of mutation is relatively slow.
