nucleus
nucleus The double-membrane-bound
organelle containing the
chromosomes that is found in most non-dividing
eukaryotic cells; it is essential to their long-term survival. It is variously shaped, although normally spherical or ovoid. It disappears temporarily during cell division. It is absent from
viruses. The chromosomes, though probably intact, are not visible when the cell is in a resting stage (i.e. not dividing). The nucleus also contains nucleoli (see
NUCLEOLUS).
