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.
The rate and pattern of sequence substitutions in the mitochondrial DNA (mtDNA) control region (CR) is of central importance to studies of human evolution and to forensic identity testing. Here, we report a direct measurement of the intergenerational substitution rate in the human CR.long this line, some work has recently been done to measure explictly the rate of substitution in mitochondrial DNA. The reference is Parsons, Thomas J., et al., A high observed substitution rate in the human mitochondrial DNA control region, Nature Genetics vol. 15, April 1997, pp. 363-367. The summary follows:
