The NucleusNear the center of the cell is a roundish or oval-shaped nucleus. The nucleus controls the growth and division of the cell. It also contains the structures that transmit hereditary traits. Enclosed by a two-layered membrane, the nucleus contains a liquid called nucleoplasm as well ...
In the past decade, evidence has accumulated that free Ca(2+) within the nucleus also plays an important messenger function. Here we review the mechanisms and effects of Ca(2+) signals within the nucleus. In particular, evidence is reviewed that the nucleus contains the machinery necessary for...
