Mitochondria are cytoplasmic organelles containing their own DNA and some enzymes that catalyse the process of oxidative phosphorylation. Mitochondria are not autonomous bodies because they require their own genes and nuclear genes to function normally. The role of mitochondria in cytoplasmic inheritance was first understood when Ephrussi and his [...]
