Membrane enclosed organelle which contains most of the cell's genetic material.
Center portion of cells essential for cell growth, nourishment and reproduction.
The central region of an atom which contains more than 99% of the atom's mass.
The largest, most prominent organelle in eukaryotic cells, the nucleus is a round or oval body that is surrounded by the nuclear envelope and contains the genetic information necessary for control of cell structure and function. It is the central cell structure that houses the chromosomes and is essential to such cell functions as growth, metabolism, and reproduction. [ Talking Glossary
the organelle in the cell body of the neuron (and all cells) that contains the genetic material of the cell (DNA in chromosomes). It is where DNA (deoxyribonucleic acid) replicates itself, and where RNA (ribonucleic acid) is made.
the membrane bound structure containing a cell's central DNA found within alleukarotic cells.
Found at the centre of an atom, the nucleus contains protons and neutrons. Classifying materials
1. The positively charged core of an atom with which is associated practically the whole mass of the atom but only a minute part of its volume. A nucleus is composed of one or more protons and an approximately equal number of neutrons. The atomic number Z of the element indicates the number of protons in the nucleus. The mass number A of the element is the sum of the protons and neutrons. 2. In biology, a definitely delineated body within a cell containing the chromosomes.
part of the cell that contains chromosomes and hereditary information, and controls the cell's growth and reproduction
control centre of the cell houses the cellâ€(tm)s DNA.
The center of an atom, a region where protons and neutrons are located, and around which electrons spin. The plural of "nucleus" is nuclei.
A region of eukaryotic cells, enclosed within a membrane, containing the DNA.
In neuroanatomy, a nucleus is a central nervous system structure that is composed mainly of gray matter, and which acts as a hub or transit point for electrical signals in a single neural subsystem. For example, the lateral geniculate nucleus mediates signals in the vertebrate visual system. The vestibular nucleus stores head motion information and guides eye movements via the vestibulo-ocular reflex.
