What must HIV surface protein do to enter a host cell?
The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.
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.
Are viruses infection proteins?
Viruses are made up of proteins (capsid) and genetic material. Virus surface protein interact with its host cell receptors for the entry (1st step in infection). Viral particle can infect the host by inserting their genetic material in to the host genome. Host synthetic machinery produce viral proteins.
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.
What are the spikes and there function in a virus?
Spikes are proteins that are part of the viral capsid/envelope (depending on if the virus is a naked virus or not). It helps with attachment to the host cell. They are derived from their host cell's own proteins (but are not the same as their hosts), and can help in evading the host cell's defenses.
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 advantage does a virus have when invading an organism if it incorporates part of a host cell membrane into its envelope?
Envelopes aid the virus in entering the host's cells. Glycoproteins on the envelope's surface are unique to the virus. They identify and bind to receptor sites on the host's cell membrane.
Where does an enveloped virus synthesize its proteins?
Viral proteins are synthesized in the cytoplasm using the host's enzymes.
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.
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.
What is the function of envelope proteins of a virus?
The function is to allow "docking" with the host cell.
