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.
Figure 13.44 shows that the combination of replication and segregation mechanisms can result in a stochastic assignment of DNA to each of the copies, that is, so that the distribution of mitochondrial genomes to daughter mitochondria does not depend on their parental origins.
