Not exact matches

6 Most of that DNA resides not in the cell nuclei, which control heredity, but in our mitochondria, the organelles (units within cells) that generate metabolic energy.

Such organelles as mitochondria, for instance, generate fuel; in plant cells, chloroplasts manufacture sugars to break down into that fuel.
