TED-Ed: The genes you don't get from your parents (but can't live without) | Devin Shuman

Mitochondria are unique organelles with their own genome, separate from the nuclear DNA. They play a crucial role in energy conversion, producing ATP from food and oxygen. Mitochondria have evolved over billions of years, originating from a symbiotic relationship with a single-celled organism. Inheritance of mitochondrial DNA is typically maternal, and these organelles replicate independently within cells. Despite their independence, mitochondria rely on nuclear DNA for certain functions. Understanding mitochondria can provide insights into human health and evolutionary history.

Describe the evolutionary relationship between mitochondria and their host cells.

What happens to mitochondrial DNA as cells replicate?
