A)Genes for both mitochondrial and chloroplast RNA polymerase are encoded in the DNA of these organelles.

The observation that genes for both mitochondrial and chloroplast RNA polymerase are encoded in the DNA of these organelles could be used as evidence for the endosymbiotic theory, as it suggests that the organelles have retained some of their bacterial genes. The other observations, such as the size of the organelles, the presence of their own DNA, and the similarity to cyanobacteria, are also consistent with the endosymbiotic theory.
