Chloroplasts and mitochondria are similar in the sense that they both contain DNA.
MITOCHONDRIA AND CHLOROPLAST:
Mitochondria is a membrane bound organelle found in eukaryotic cells. Mitochondria is the energy production site of cells because it is where cellular respiration takes place.
Chloroplast is another membrane-bound organelle in eukaryotic cells. They are the site of photosynthesis in plants.
Mitochondria and chloroplast are both involved in energy conversion in cells because electron transportchain occurs in both organelles.
However, another similarity between these two organelles is that they contain extra-chromosomal DNA.
DNA has a double helix structure. The outer edges are formed by alternating deoxyribose sugar molecules and phosphate groups. The two strands run in opposite directions one going in a 3 to 5 the other going in a 5 to 3.
