Question
Which one of the following has their own DNA?(a) Vacuole (b) Mitochondria (c) Golgi bodies (d) Ribosome
Solution
The answer is (b) Mitochondria. Mitochondria have their own DNA, which is separate from the nuclear DNA found in the nucleus of the cell. This DNA is circular and is similar to the DNA of bacteria, supporting the theory that mitochondria were once free-living bacteria that were incorporated into cells in a symbiotic relationship.
