| The RNA-binding motif is a characteristic feature of the nucleocapsid and is widespread among retroelements. |
|
| The DNA is enclosed in a nucleocapsid, or core antigen, which is surrounded by a spherical envelope. |
|
| Surrounding the nucleocapsid is an outer lipid envelope made from the membrane of the host cell. |
|
| In some viral families, the nucleocapsid is surrounded by a peripheral optional structure called the envelope. |
|
| In an acidic environment, the membrane of an enveloped virus fuses with the endosome membrane, and the viral nucleocapsid is released into the cytoplasm. |
|
| Coronaviridae is generally considered to contain two genera, Coronavirus and Torovirus, which differ in nucleocapsid morphology, the former being helical and the latter being tubular. |
|
| Viral proteins, in particular gp120 and nucleocapsid proteins, are retained in their native and functional state. |
|
| The single stranded RNA is tightly bound to nucleocapsid proteins, p7 and enzymes needed for the development of the virion such as reverse transcriptase, proteases, ribonuclease and integrase. |
|
| The nucleoprotein structure defined by the nucleic acid and the internal proteins is called nucleoid and the group nucleoid and capsid constitute a functional unity which is called nucleocapsid. |

| Utilization of autopsy RNA for the synthesis of The nucleocapsid antigen of a newly recognized virus associated with hantavirus pulmonary syndrome. |
|
| The use of whole virus provides additional structural and nonstructural protein antigens, including envelope, membrane, nucleocapsid, and diverse replicase proteins. |
|
| A polyhistidine-tagged recombinant nucleocapsid protein of SNV was expressed in Saccharomyces cerevisiae and purified by nickel chelation chromatography. |
|
| Essentially, virosomes represent reconstituted empty influenza virus envelopes, devoid of the nucleocapsid including the genetic material of the source virus. |
|
| These segments are circular because of their 5' and 3' complementary termini and complex with a nucleocapsid protein to form individual L, M, and S nucleocapsids. |
|
| Sequence analysis of the genes encoding the nucleocapsid protein and phosphoprotein of phocid distemper virus, and editing of the P gene transcript. |
|
| Nucleocapsid surrounded by the tegument that consists of globular material, which is frequently asymmetrically distributed and may be variable in amount. |
