Why do organelles like mitochondria and chloroplasts have their own DNA? (1 point) They are responsible for their own replication and division inside the cell ODNA is used to code for proteins , which these organelles synthesize . They used to be free-living prokaryotes that functioned as unicellular organisms . All organelles have their own DNA and these two demonstrate that property .

Answer 1

Mitochondria and chloroplasts have their own DNA because they used to be free-living prokaryotes that functioned as unicellular organisms. This endosymbiotic theory suggests that they were engulfed by ancestral eukaryotic cells, establishing a symbiotic relationship, which is why they retain their own DNA for some of their functions.
