What features of the similarity between mitochondria and prokaryotes allowed us to put forward a symbiotic theory of the origin of eukaryotic cells?
1) They have two fully closed membranes. In this case, the external is similar to the membranes of vacuoles, the internal – bacteria.
2) Propagated by binary division (and sometimes divide independently of cell division).
3) Genetic material – circular DNA, not associated with histones, has its own protein synthesis apparatus – ribosomes and others. Prokaryotic type ribosomes.
