Some are found in the mitochondria, “the organelles that house the cellular machinery for oxidative metabolism that produces energy” (Klepinger, 2006, p. 149). Mitochondria DNA is quite small as compared to nuclear DNA but has a very high copy number as compared to the nuclear DNA. Klepinger also explains that mitochondrial DNA mutates so fast and a single individual can show a mixture of variants, which is not seen, in nuclear DNA. Mitochondrial DNA is inherited exclusively from the maternal lineage (Saferstein, 2011). Nuclear DNA sources include: blood, soft tissue samples, serum, semen, vaginal fluids, and bone marrow.
