There is a hypothesis of symbiogenesis, according to which mitochondria and chloroplast originated from prokaryotic cells. Give at least five evidence to support her.

Mitochondria and plastids;
– have two completely closed membranes. In this case, the external is similar to the membranes of vacuoles, the internal – bacteria.
– multiply by binary division (and sometimes divide independently of cell division), are never synthesized de novo.
– genetic material – circular DNA that is not associated with histones (According to the proportion of HC of mitochondrial DNA and plastid, it is closer to bacterial DNA than to eukaryotic nuclear DNA)
– have their own apparatus for the synthesis of protein – ribosomes, etc.
– ribosomes of prokaryotic type – with a sedimentation constant of 70S. The structure of 16s pRNA is close to bacterial.
– some of the proteins of these organelles are similar in their primary structure to similar bacteria proteins and are not similar to the corresponding cytoplasmic proteins.
