Which of the following is TRUE for both chloroplasts and mitochondria?

The chloroplast is important for photosynthesis in plants and the mitochondria is essential for cellular respiration in both plants and animals. Both are organelles that have a double membrane and have their own DNA. The DNA in these organelles is maternal DNA, that is only inherited by the mother of the organism. DNA in all forms is double stranded and neither the mitochondria nor the chloroplast contain any forms of RNA. [Life Science]
