Mitochondrial DNA Use in Forensics
The mitochondria has some unique DNA sequences. All of these genes come from only your mother. A single mitochondrion contains several loops of DNA.
Mitochondria are found in all human cells. When Mitochondrial DNA is used in Forensics Nuclear DNA is significantly degraded. Nuclear DNA is present in small quantities. Authorities cannot obtain a reference sample from an individual who is long deceased or missing.
Mitochondrial DNA Fingerprints In situations where authorities cannot obtain a reference sample from a missing child, a mitochondrial DNA reference sample is obtained from maternally related relatives. Mitochondrial DNA can be amplified by using polymerase chain reaction.
