Mitochondrial DNA Analysis
at the FBI Laboratory
Figure 3
Organization of mtDNA
The mtDNA genome is approximately
16,569 bases in length and is divided into two sections: coding
and noncoding. The noncoding region is also called the control
region and contains two highly polymorphic regions called Hypervariable
Regions I and II (shown in red and yellow in the diagram). Each
of these hypervariable regions is approximately 300 bp in length.
The FBI Laboratory sequences both of these regions in a forensic
case.
