The nucleus is a spherical-shaped organelle present in every eukaryotic cell. It is the control center of eukaryotic cells, responsible for the coordination of genes and gene expression. The structure of a nucleus encompasses nuclear membrane, nucleoplasm, chromosomes and nucleolus.uclear Membrane. The nuclear membrane is a double-layered structure that encloses the contents of the nucleus. The outer layer of the membrane is connected to the endoplasmic reticulum. A fluid-filled space or perinuclear space is present between the two layers of a nuclear membrane.
