This final stage of the mitochondrial evolutionary pathway may serve as a model to explain events at their very beginning such as the initiation of protein import. The only eukaryotic organism known to lack mitochondria is the oxymonad Monocercomonoides species. (4 marks) 3. Monocercomonoides actually managed to replace the mitochondria’s genes for building iron-sulfur complexes with genes from another bacteria for a very different system, called cytosolic sulfur.
