What makes a viral capsid?
Protein of course :P
What occurs during viral uncoating?
The capsid breaks apart, releasing the viral genome.
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 a peplon?
Peplon or Peplomer is a glycoprotein spike on viral capsid or viral envelope. They only bind to certain receptors.
A viral capsid is composed of?
it is composed of individual morphological units called capsomers.
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 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.
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 are capsid spikes and what are they for?
The spikes you are referring to I am assuming concern viruses. They are located on the envelope surrounding the capsid, typically made up of the host cell material. The spikes themselves are of protein and match with receptors on the host cell. This is kind of like a key to a door. The virus sheds the envelope when entering the host cell, then sheds the capsid, releasing the nucleic acid (DNA/RNA) causing a viral infection to occur.
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.
