Web1. 1) You're correct, there are mutations that are not harmful to the mitochondria or cell. 2) Mitochondrial mutation is probably more likely to be harmful than nuclear DNA mutation since it is much less vast. Nuclear DNA is much larger and thus there is less change to mutate something important. WebBoth mitochondria and chloroplasts contain their own DNA and ribosomes.
