Explanation
The nucleus, mitochondria, and chloroplasts each contain their own DNA. These organelles are membrane-bound structures within cells that carry out distinct functions. The nucleus serves as the cell's control center and stores most of the genetic information. Mitochondria generate energy in animal cells, while chloroplasts perform a similar energy-producing role in plant cells. Because all three have their own DNA, the correct answer is 'All of the above.'
