nucleocapsid

 [noo″kle-o-kap´sid]
a unit of viral structure, consisting of a capsid with the enclosed nucleic acid; it is generally inside the cytoplasm.

vi·ri·on

(vī'rē-on, vir'ē-on),
The complete virus particle that is structurally intact and infectious.

nucleocapsid

/nu·cleo·cap·sid/ (noo″kle-o-kap´sid) a unit of viral structure, consisting of a capsid with the enclosed nucleic acid.

Nucleocapsid in a schematic diagram of HIV-1; molecules of protease, integrase, and reverse transcriptase, which also occur within the capsid, are omitted for simplicity.

nucleocapsid

(no͞o′klē-ō-kăp′sĭd, nyo͞o′-)
n.
The nucleic acid of a virus together with the protein coat that encloses it.

nucleocapsid

[no̅o̅′klē·ōkap′sid]
Etymology: L, nucleus + capsa, box
a viral enclosure consisting of a capsid or protein coat and a nucleic acid that it surrounds. Some viruses consist solely of bare nucleocapsids; others have more complex enclosures.

vi·ri·on

(vī'rē-on)
The complete virus particle that is structurally intact and infectious.

nucleocapsid

a minimum unit of viral structure, consisting of a protein capsid with the enclosed nucleic acid. For some viruses the nucleocapsid is enclosed within an envelope.

Bone marrow mononuclear cells from patients with Paget's disease contain measles virus nucleocapsid messenger ribonucleic acid that has mutations in a specific region of the sequence.
Nascent particles were formed by the juxtaposition of viral nucleocapsids along cytoplasmic membranes of the budding compartment (the membrane region between the rough endoplasmic reticulum and the Golgi complex) or occasionally on the membranes of the rough endoplasmic reticulum that form the outer layer of the nuclear membrane.
Cytoplasmic inclusions of darkly staining viral nucleocapsids were mostly found in association with virus-containing vesicles or double-membrane vesicles (Figures 1B and 3D).
In addition, mice infected with LDV or immunized with inactivated virions do not generate Abs to the N-protein (38,39), apparently because the viral envelope or its proteins interfere with the immunogenicity of the N-protein since a mAb to the N-protein was generated by immunizing mice with isolated nucleocapsids (40).
The primary structural proteins of arteriviruses are the nucleocapsid (N) protein, the integral membrane/matrix (M) protein, and the primary envelope glycoprotein, GP5 (10-12).
The first 8 to 13 nucleotide bases at the 3' ends of all three RNA segments have a sequence that is conserved in the viruses of this genus, with a complementary consensus sequence occurring at the 5' end; the ends of the segments are noncovalently linked so that the RNA occurs in a loosely bound circular configuration within the nucleocapsids (11).
