What vitamins are found in viruses?
Virus are not made up of vitamins, but nucleic acids and proteins known as capsid.
What are proteins found on the outside of cells and viruses called?
Viruses are composed of two main parts an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA. Some of these have an envelope over the capsid. The ones that do not are said to be naked. The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell. The naked viruses are more resistant to changes in the environment.
What part of the virus remains outside the bacterium?
The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell. This capsid is left behind. If the capsid has an envelope, that is also left behind. The DNA or RNA enters the cell.
What is the protein coat that surounds a virus called?
The envelope.
What parts of a virus allow it to attach to a cell?
The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.
What part of virus allows it to attach to a cell?
The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.
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.
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.
IS HPV single or double stranded?
circular double stranded DNA protected by capsid proteins
What does surrounds the hereditary material of a virus?
The capsid. Made of protein, and sometimes various types of proteins.
What two things are viruses typically made of?
Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA. Some of these have an envelope over the capsid. The ones that do not are said to be naked. The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell. The naked viruses are more resistant to changes in the environment.
What is responsible for the specificity of viruses?
Viruses have proteins in their capsid which match proteins in the membrane of their preferred host. This produces the ability to "dock" and then enter the host cell.
