What is Nucleus?

What is nucleus?

Anything that works, works best when it is controlled. For cell, “headquarters,” or the control center is the gene-containing nucleus (nucle kernel). The genetic material

, or deoxyribonucleic acid ( DNA ), is much like a blueprint that contains all the instructions needed for building the whole body so, as one might expect human DNA differs from that of a frog. More specifically, DNA has the instructions for building proteins, DNA is also absolutely necessary for cell reproductive. A cell that has lost or ejected its nucleus (for whatever reason) is programmed only to die. While most often oval or spherical, the shape of the nucleus usually conforms to the shape of the cell. For example, if the cell is elongated, the nucleus is usually extended as well. The nucleus has three recognizable regions or structures; the nuclear envelope, nucleoli, and chromatin.
