Abstract
The DNA of living organisms is packaged into chromosomes differently in different species, but typically following a standard set of "rules." Understanding how DNA can be packaged for different species provides a better understanding of life and the genetic rules that must be followed, and the "rules" that can be broken. Mitochondria are crucial subcomponents of cells, providing the energy for life. Mitochondria always have their own mtDNA. In our study, we have learned that chewing lice mtDNA differs from that of other animals by spreading the genes across 12 separate small, circular chromosomes instead of one large, circular chromosome. We sequenced and mapped these minicircles to better understand the organization and rearrangement of genes through evolutionary time. Recognition of developmental rearrangements within the mtDNA allows for greater understanding of potential conditions that may lead to mitochondrial dysfunction. This knowledge may benefit the development of treatments for devastating mitochondrial diseases.

Characterization of mtDNA Minicircles in a Chewing Louse, Geomydoecus centralis
The DNA of living organisms is packaged into chromosomes differently in different species, but typically following a standard set of "rules."
