Which organelle contains its own DNA and is inherited maternally?

Explanation:
The important idea here is that mitochondria carry their own genetic material and are passed on from mother to offspring. Mitochondrial DNA is circular and resides inside the organelle, separate from the cell’s nuclear DNA, and mitochondria replicate within the cell. In fertilization, the egg supplies most of the cytoplasm and its mitochondria, while sperm mitochondria are typically not transmitted, so mitochondrial DNA shows maternal inheritance. The nucleus contains DNA inherited from both parents, and the Golgi apparatus and ribosomes do not contain DNA.
