Which of the features characteristic for (most) mitochondria and chloroplasts is NOT indicative of the organelles` endosymbiotic origin: a) possession of own, usually circular DNA, and own ribosomes;
structure and compostion of the organelles` ribosomes;
the way these organelles multiplicate;
presence of numerous introns in the organelles` genes;
possession of own, usually circular DNA, and own ribosomes;
all of the above features reflect the similarity to prokaryotes, therefore support the endosymbiotic theory of the organelles`origin.
The fluid outside the thylakoids is the (a) , which contains the chloroplast DNA and ribosomes as well as many enzymes.
