DNA in prokaryotes frees in the cytoplasm, while in eukaryotes (like humans) DNA is in the nucleus.
Human DNA is found in the cells that make up your tissues and organs: nerve cells, liver cells (liver), skin cells ... They are extremely numerous, more than 50 000 billion and have very diversified functions! Most of our cells are microscopic (20 to 30 micrometers) and contain an even smaller nucleus structure.
Each nucleus contains the genetic material of the cell, the chromosomes.
Mitochondrial DNA can also be found in mitochondria, but mitochondria are much smaller than nuclear DNA.
