摘要

The nuclear and mitochondrial genomes co- evolve to optimize approximately 100 different interactions necessary for an efficient ATP-generating system. This coevo- lution led to a species-specific compatibility between these genomes. We introduced mitochondrial DNA (mtDNA) from different primates into mtDNA-less human cells and selected for growth of cells with a functional oxidative phosphorylation system. mtDNA from common chimpanzee, pigmy chimpan- zee, and gorilla were able to restore oxidative phosphorylation in the context of a human nuclear background, whereas mtDNA from orangutan, and species representative of Old- World monkeys, New-World monkeys, and lemurs were not.
