Nucleus

** __//THE CELL NUCLEUS//__ **



**__Introduction:__** The Nucleus is always located inside of the cell, but there is no specific point in the cell in which the nucleus stays. The Nucleus is a large, membrane-bound, usually spherical, protoplasmic structure within a living cell, containing the cell's hereditary material and controlling it's metabolism, growth, and reproduction.

[|Nucleus Information]
 * Bounded by a double membrane called the nuclear envelope.
 * The nucleus also contains the nucleolus which helps to synthesize ribosomes.
 * The nucleolus contains nuclear organizers which are part of chromosomes with the genes for ribosome synthesis on them.
 * Most cells have just one nucleus and are called uninucleate, while some can have two or more nuclei and suhc cells are know as biunicleate and multinunicleate.
 * There exists some matured cells where nuclei may be completely absent.
 * Nucleus is the place for DNA transcription in which messenger RNA are produced with which synthesize protein.

The nucleus stores the hereditary material, the genes in the form of long and thing DNA strands are referred to as chromatin. The nucleus exchange hereditary molecules (RNA and DNA) between it and the rest of the cell. During the cell division, chromatins are arranged into chromosomes. As the nucleus regulates the integrity of genes and gene expression, it is also referred to as the control center of a cell. The cell nucleus contains all the genetic material of an organism like chromosomes, DNA, genes, etc.

Robert Brown named the Nucleus. Robert Brown is best known for his description of the natural continuous motion that is named for him. In addition, he recognized the fundamental distinction between the conifers and their allies (gymnosperms) and the flowering plants (angiosperms), recognized and named the nucleus as a constant constituent of living cells in most plants, and improved the natural classification of plants by establishing and defining new families and genera.
