Nucleus (Dairy Production)

A complex protoplasmic body within a living cell that contains the cell's hereditary material and controls its metabolism, growth and reproduction.

Nucleus (Ear Surgery)

The center of the cell containing the genetic information (genes, chromosomes, DNA, etc.) The appearance of the nucleus is used as a criterion to determine the malignant potential of a cell of tissue.

Nucleus (Entomological)

The spheroid body within a cell that has the major role in controlling and regulating the cell's activities and contains the hereditary units or genes.

Nucleus (Environmental Toxins)

The central part of an atom that contains protons, neutrons and other particles.

Nucleus (Evolution)

A region of eukaryotic cells, enclosed within a membrane, containing the DNA.

Nucleus (Gene Testing)

The cell structure that houses the chromosomes.

Nucleus (Genetics)

The structure in the center of each cell that holds chromosomes.

Nucleus (Genetics and Food)

The control centre of the cells of all living things. The nucleus contains the genetic material of an organism (chromosomes, DNA, genes).

Nucleus (Genetics and Genealogy)

The cellular organelle, i.e., the central cell structure, that houses the chromosomes.

Nucleus (Genome)

The cellular organelle in eukaryotes that contains most of the genetic material.

Nucleus (HIV and AIDs)

1. The central controlling body within a living cell, usually a spherical unit enclosed in a membrane and containing genetic codes for maintaining the life systems of the organism and for issuing commands for growth and reproduction. 2. The nucleus of a cell is essential to such cell functions as reproduction and protein synthesis. It is composed of nuclear sap and a nucleoprotein-rich network from which chromosomes and nucleoli arise, and is enclosed in a definite membrane.

Nucleus (Hepatitis C)

The generally oval protoplasmic body in the center of the cell which contains the genetic material and is surrounded by a nuclear membrane; an essential organelle that controls metabolism, growth, and reproduction.

Nucleus (Huntingtons Disease)

1. A spherical body within the cell that is enclosed by a double membrane. The nucleus contains the chromosomes and is the information center of the cell. 2. A collection of nerve cells in the brain that are anatomically discrete and which typically serve a particular function. (Plural form: nuclei.)

Nucleus (Insect)

The spheroid body within a cell that has the major role in controlling and regulating the cell's activities and contains the hereditary units or genes.

Nucleus (MRI)

The core or center part of an atom, which contains protons having a positive charge and neutrons having no electrical charge, except in the common isotope of hydrogen, where the nucleus is a single proton.

Nucleus (Medical)

The center or most important point of an object

Nucleus (Metal)

(1) The first structurally stable particle capable of initiating recrystallization of a phase or the growth of a new phase, and separated form the matrix by an interface. (2) The heavy central core of an atom, in which most of the mass and the total positive electrical charge are concentrated.

Nucleus (Microbiology)

A cellular inclusion composed of chromatin; morphology often used to help identify intestinal protozoa (Entamoeba and Dientamoeba spp.).

Nucleus (Nuclear)

The core of the atom, where most of its mass and all of its positive charge is concentrated. Except for 1H, the nucleus consists of a combination of protons and neutrons.

Nucleus (Nuclear Science)

The core of the atom, where most of its mass and all of its positive charge is concentrated. Except for hydrogen, it consists of protons and neutrons.

Nucleus (Oceanography)

A round body inside a cell that acts as the control centre for the cell and contains genetic information.

Nucleus (Physics High Energy)

A collection of neutrons and protons that forms the core of an atom (plural: nuclei).

Nucleus (Pituitary)

The center of the cell containing the genetic information (genes and chromosomes, DNA, etc.). The appearance of the nucleus is used as a criterion to determine the malignant potential of a cell or tissue.

Nucleus (Planetary Science)

(see comet) Kilometer-sized "dirty snowball" composed of dust (refractory material) and primarily water-ice which gives rise to all of the features observers associate with comets. As the nucleus approaches the Sun, the temperatures rise sufficiently to cause the sublimation of the ices. As the gas leaves the nucleus, it is able to drag some of the dust with it in the low gravity. Sunlight reflected off the dust is what we see as the yellowish coma and tail of the comet, and interaction of the solar radiation with the gases gives us the characteristic blue appearance of the plasma tail.

Nucleus (Prostate Cancer)

The main controlling body of a living cell

Nucleus (Robotics)

The central part of an atom that contains the protons and neutrons. It contains most of the mass of an atom. Ernest Rutherford found that atoms have nuclei in 1909.

Nucleus (Sanitation)

(1) The small, positively charged core of an atom. It is only about 1/10,000 the diameter of the atom but contains nearly all the mass. Except for ordinary hydrogen, all nuclei contain both protons and neutrons. The nuclear properties of an isotope of a given element are determined by both the number of neutrons and number of protons. (2) The structure of a cell that contains the genetic information coded in the chromosomes.

Nucleus (Science)

The central core of an atom in which the atom's protons and most of its mass are found; the control center of a cell; surrounded by its own membranes

Nucleus (Skin Cancer)

The genetic control center of a cell, made of DNA. The nucleus is composed of chromosome genes that are tightly packed and pick up the dark purple stain hematoxylin. Cancer or abnormal cells often show irregularities in the nucleus.

Nucleus (Solar Physics)

The positively charged core of an atom, consisting of protons and neutrons (except for hydrogen), around which electrons orbit.

Nucleus (Stem Cells)

A part of the cell, situated more or less in the middle of the cell, that is surrounded by a specialized membrane and contains the DNA of the cell. This DNA is packaged into structures called chromosomes, which is the genetic, inherited material of cells.

Nucleus (Universe)

The core of an atom, consisting of protons and neutrons.

Nucleus (Vitamins)

The ‘heart’ of a cell, ringed by a membrane and containing the controlling genes.
