www.clevelandmetroschools.orgWhat structure manages cell processes? The nucleus is the cell’s managing structure. Most of the cell’s genetic material (DNA) is in the nucleus. DNA defi nes the cell and controls protein production. A nuclear envelope surrounds the nucleus. Substances pass through the nuclear envelope to move in and out of the nucleus.
