What occurs during viral uncoating?
The capsid breaks apart, releasing the viral genome.
What is a peplon?
Peplon or Peplomer is a glycoprotein spike on viral capsid or viral envelope. They only bind to certain receptors.
How does a virus acquire a capsid?
Within the cell it invades it's genetic material commanders the transcription machinery and the cell invaded cranks out the proteins needed to make the viral capsid.
What is the nucleic acid core in a virus called?
the "core" of a virus is the nucleic acid (either DNA or RNA) that makes up the viral genome. this core contains all the genetic information of that virus, and is enclosed within the protein coat known as the capsid.
What is bacteriophage capsid?
Correct. For APEX it is, A protective shell around a virus.
What is the protein coat that surounds a virus called?
The envelope.
A viral capsid is composed of?
it is composed of individual morphological units called capsomers.
What do you call the protein shell of a virus?
A capsid is the protein shell of a virus. It consists of several oligomeric structural subunits made of protein called protomers. The observable 3-dimensional morphological subunits, which may or may not correspond to individual proteins, are called capsomeres. The capsid encloses the genetic material of the virus.
What part of a virus does not enter the host?
Generally, the protein coat that surrounds the viral genetic material and any reverse trascriptase enzymes. This capsid stays outside the cell attacked while the genetic material and whatever else is needed is injected into the cell or the capsid merges with the cell membrane and the vital viral material enters the cell.
What is an optional 3rd viral component that if present will help a virus to enter the host cell?
The three are a capsid, envelope and spikes. The envelope is optional.
What are the spikes and what is their function?
A part of the viral envelope/ capsid which are proteins is known as spikes. They help evade the defenses of the host cell are obtained from their protein.
How do enveloped viruses differ from nonenveloped viruses?
DNA or RNA + Structural Proteins + Enzymes and nucleic acid binding proteins = Nucleocapsid (may be the same as a virion or surrounded by an envelope) If there is only a Nucleocapsid, then it is considered a Naked Capsid Virus If there is a Nucleocapsid with the addition of Glycoproteins and a Membrane, then the virus is considered enveloped.
