Why is protein synthesis important for cells and viruses?
Protein synthesis is important for viruses because the virus forces the host cell to make proteins that the cell does not need, but the virus does to repoduce. Protein synthesis is important for cells because the proteins are essential for all cellular activites.
What can you conclude about the surface proteins of viruses for which effective vaccines exist?
In order to neutralize the virus, the proteins fro the surface of the virus is used. There are more than a single surface glycoprotein in a single virus and the best antigen must be chosen.
How does an active virus multiply?
Once inside a cell, a virus's genetic material takes over of the cell's functions. It instructs the cell to produce the virus's proteins and genetic material. These proteins and genetic material then assemble into new viruses.
Which cell is bigger virus eukaryotic cell prokaryotic cell proteins lipids?
I will arrange these items in order; largest to smallest. eukaryotic cell----prokaryotic cell---virus Proteins---lipids ( I would not swear by this second answer )
A strand of hereditary material surrounded by a protein coating?
DNA (Deoxyribose nucleic acid) and it is surrounded by (held in position by) histone proteins forming octamers.
How does mRNA lead to new viral particles?
mRNA is a "message" that is transcribed into proteins. The proteins form the capsid and other proteins the virus needs. The virus also needs genetic material so it can propagate in other cells. If a virus is a + strand ssRNA (coding strand, analagous to mRNA) just that RNA could lead to a viral infection.
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.
Proteins on the outside of the aids virus bind to what?
proteins on the surface of red blood cells

How does a host living cell face with an enemy virus?
A virus and a cell have to have matching "docking" proteins for the virus to invade. Otherwise the virus is blocked.
Where does an enveloped virus synthesize its proteins?
Viral proteins are synthesized in the cytoplasm using the host's enzymes.
What is antigenic drift?
The genome of viruses can mutate over time through a variety of mechanisms. Some viruses are more prone to these mutations than others. When the genome changes, this changes the proteins that are expressed by the virus, included the proteins that are present on the surface of the virus. These proteins are the antigens that are recognised by the host immune system and which trigger the immune response. Antigenic drift is when the genome of the virus mutates thus changing the antigens expressed by the virus. This means that an individual immunized against a virus may not be protected if the virus undergoes antigenic drift as the proteins present of the surface of the virus are not the same as the virus against which the individual was immunized.
What is the purpose of proteins on outer coat of a virus?
To match and dock with proteins on the outside of cells they are going to enter.
What can you conclude about the surface proteins of viruses for which effective vaccines exist?
In order to neutralize the virus, the proteins fro the surface of the virus is used. There are more than a single surface glycoprotein in a single virus and the best antigen must be chosen.
What is the protein coat that surounds a virus called?
The envelope.
Why do proteins establish the host range of a virus?
It all depends on what you mean by your question. Both the host cell and the virus have proteins that must match for the virus to enter the cell. The more these match, the greater number of species of plants and animals that will be affected.
