nucle-, nucleo-, nuc- +
(Latin: nut, kernel of a nut; stone of a fruit; central part of a cell)
bionucleonics
The study of the biological applications of radioactive and rare stable isotopes.
internuclear
1. Located or occurring between nuclei.
2. Pertaining to or affecting structures between nuclei, as internuclear ophthalmoplegia.
3. Between the nuclear layers of the retina.
intranuclear
1. Existing or occurring within the nucleus of an atom or within the nucleus of a cell.
2. Within the nucleus of a cell; as, the intranuclear network of fibrils, seen in the first stages of karyokinesis (series of active changes that take place in the nucleus of a living cell in the process of division).
macronucleus (s), macronuclei (pl)
The larger of two nuclei in most ciliate protozoans, involved in nonreproductive functions; such as, feeding and metabolism.
meganucleus
The larger of two nuclei present in ciliate protozoans, which controls the nonreproductive functions of the cell.
micronucleus (s), micronuclei (pl)
The smaller of the two nuclei in the cells of ciliate protozoans. It contains genetic material and is involved in sexual reproduction.
mononuclear
1. A description of a cell that has a single nucleus.
2. An organic compound with a molecular structure containing only one ring of atoms.
nuclear
1. Relating to or constituting the nucleus of an atom.
2. A reference to or constituting the nucleus of a cell.
3. Constituting or like a nucleus: "Annexation of the suburban fringe by the nuclear metropolis."
4. Deriving destructive energy from the release of atomic energy.
nucleate
1. To bring together into a nucleus.
2. To act as a nucleus for.
3. To provide a nucleus for or to form a nucleus.
nucleation
1. The process by which ice crystals and rain drops form in clouds around a solid core.
2. The formation of mineral crystals from a melt, often around a core of solid material.
3. The formation of cell nuclei.
nucleiform
Formed like a nucleus or kernel.
nuclein
1. Any of the substances present in the nucleus of a cell, consisting chiefly of proteins, phosphoric acids, and nucleic acids.
2. A decomposition product of nucleoprotein intermediate between native nucleoprotein and nucleic acid.
It is a colorless, amorphous compound, soluble in dilute alkalis, but insoluble in dilute acids. The nucleins consist of nucleic acid and bases which vary in the different nucleins.
nucleocapsid
1. The basic viral structure consisting of a core of nucleic acid surrounded by a protein coat.
2. The genome plus the protein coat of a virus.
The nucleic acid (RNA or DNA) of the virus is its genome. The protein coat is its capsid (which is protein coat of a virus).
nucleocosmochronology
A technique that attempts to estimate the age of astronomical objects by measuring the relative abundances of isotopes (any of two or more atoms of an element having the same number of protons, but a different number of neutrons in its nucleus).
nucleoid
1. Resembling a nucleus.>BR?
2. The aggregated DNA of a bacterium, seen as a distinct region inside the cell.
3. The nuclear region of a bacterium, consisting of a dense, centrally located, irregularly shaped region containing DNA material without a surrounding nuclear membrane.
4. The genetic material (nucleic acid) of a virus, situated in the center of the virion (complete virus particle with its DNA or RNA core and protein coat as it exists outside the cell).
