Message is only translated in the cytoplasm, everything else is done in the nucleus. A third cellular space is the endoplasmic reticulum, a way to move around in the cell independent of the cytoplasm. Bacteria were already feeding on other bacteria. One time an aerobic bacterium, got absorbed by the host cell (another bacterium) and it took the plasma membrane, and now it takes pyruvate from the cytoplasm and gives back. Gcat pairing ratios are consistent with bacteria. Diploidy provides a second chromosome for back-up function and protects the originality.
