The term nucleus has two main meanings in science. The center of a cell contains a cell nucleus, which can be defined as an organelle which contains the genetic material of the organism. And the center of an atom contains the atomic nucleus, which can be defined as the part of the atom which contains protons and/or neutrons (all atoms except for the lightest hydrogen isotope contain both protons and neutrons).
