Where is DNA found?

Humans and other sophisticated creatures have a tiny quantity of DNA in cell structures known as mitochondria, in addition to the DNA found in the nucleus. Mitochondria produce the energy that cells require to function effectively. Organisms inherit half of their nuclear DNA from the male parent and half from the female parent during sexual reproduction. However, all mitochondrial DNA is inherited from the female parent. This is due to the fact that only egg cells, not sperm cells, retain their mitochondria throughout fertilization.
