The correct answer is: Nucleus
- DNA or deoxyribonucleic acid is the genetic material of humans and almost all other organisms.
- Almost all cells in the human body have the same DNA. Most of the DNA is present in the nucleus (where it is called nuclear DNA), but a small amount is also present in the mitochondria (called mitochondrial DNA or mtDNA).
- Mitochondria are structures within cells that convert energy from food into a form that the cell can use.
