  fails?
• 12. What did the main executor say about the
  daughters during the execution?

Mitochondrial DNA

• Although most DNA is packaged in chromosomes
  within the nucleus, mitochondria also have a
  small amount of their own DNA. This genetic
  material is known as mitochondrial DNA or mtDNA.

Mitochondria are structures within cells that
convert the energy from food into a form that
cells can use. Each cell contains hundreds to
thousands of mitochondria, which are located in
the fluid that surrounds the nucleus (the
cytoplasm).

Mitochondrial DNA

• The Majority of human cells contain hundreds of
  copies of mtDNA genomes, as opposed to two copies
  of the DNA that is located in the nucleus. This
  high copy number increases the likelihood of
  recovering sufficient DNA from compromised DNA
  samples, and for this reason, mtDNA can play an
  important role in missing persons investigations,
  mass disasters, and other forensic investigations
  involving samples with limited biological
  material.
