Mitogenomic data to study the taxonomy of Antarctic springtail species (Hexapoda: Collembola) and their adaptation to extreme environments
Mitochondrial DNA (mtDNA) encodes for proteins mainly involved in the oxidative phosphorylation process, and due to its molecular features, it is one of the most used molecular markers for phylogenetic and taxonomic purposes. Since mitochondria are the primary source of energy for aerobic organisms,...

Mitochondrial DNA (mtDNA) encodes for proteins mainly involved in the oxidative phosphorylation process, and due to its molecular features, it is one of the most used molecular markers for phylogenetic and taxonomic purposes.
