the hypothesis? To which
other cellular organelles can
the hypothesis also be
applied?

It is presumed mitochondria were
primitive prokaryotes that were
in mutualism by
anaerobic eukaryotes, receiving
from these beings
offering energy to . This hypothesis
is the endosymbiotic hypothesis
the origin of .

The hypothesis is by some
molecular such as the
mitochondria have their
independent DNA and synthesis
machinery, with own RNA and
, and that they selfreplicate.

The endosymbiotic can be
applied chloroplasts too. It
supposed that these were
primitive photosynthetic
because they have own DNA, RNA
ribosomes and they self replicate too.
