An organism’s DNA is stored in the cell nucleus, an organelle (cell organ) in the cytoplasm (cell fluid) of a cell. Cells with a nucleus have other organelles and are therefore mostly a lot larger than cells with no nucleus.

Own domain
Cells of organisms including animals, plants and fungi have a cell nucleus. These organisms are called eukaryotes (from the Greek ‘eu’ meaning ‘true’ and ‘karyon’, ‘kernel’). All types with a cell nucleus belong to the eukarya, one of the three domains of life. The other two are the bacteria and the archaea. These micro-organisms have no cell nucleus and are called prokaryote (pro=before, karyos=kernel).
Our own kernel
Humans also belong to the eukarya domain. All the cells in our bodies have a cell nucleus which contains our DNA. The only exception is the red blood cell which does not have a nucleus.
