If Sgt. Joe Friday was around today he might be saying "Just the DNA, ma'am," instead of "Just the facts, ma'am." Mitotyping Technologies performs mitochondrial DNA sequencing analysis (when there is insufficient biological material for nuclear DNA typing) for criminal investigation, post-conviction exoneration, determination of maternal relatedness, and missing-persons searches. The company focuses on the analysis of the genetic marker mitochondrial deoxyribonucleic acid (mitochondrial DNA), which is found not in a cell's nucleus, but in its mitochondria or respiratory organ elles. Mitotyping Technologies works with difficult samples (naturally shed hairs, hair fragments, and aged skeletal material).
