6 © 2014 Pearson Education, Inc. Which of the following is not an argument for the theory that mitochondria and chloroplasts evolved from prokaryotic endosymbionts? A.Mitochondria and chloroplasts have double membranes. B.Mitochondria and chloroplasts have their own ribosomes. C.Mitochondria and chloroplasts have their own DNA. D.The mitochondrial and chloroplast genomes are circular. E.All of the above support the endosymbiotic theory.
