What is most important for attachment of a virus to a host cell?
While we are constantly referring to bi-lateral specificity, as in the functions of Dna, here is a case where a virus offers out it's 'hand': it seems likely that it expects to reach for, find and attach to some outstretched Cell Membrane Component.
Which does not refer to the shape of a virus?
A bacillus does not refer to the shape of a virus. The capsid of a virus is what determines the shape of a virus.
What are spikes on viruses made of?
Spikes on viruses are made up of proteins that are used to attach the virus to host cells. These proteins play a critical role in allowing the virus to enter and infect host cells by binding to specific receptors on the cell membrane.
What does the protein structure of a virus have to do with the attachment to host cells?
The protein structure of a virus typically includes specific proteins on its outer surface that help it attach to receptors on host cells. This attachment is crucial for the virus to gain entry into the host cell, infect it, and replicate. The binding specificity between viral proteins and host cell receptors is a key determinant of the virus's ability to infect specific cell types.
True of false when a virus is active the cell makes the virus's proteins and genetic material and new viruses are made?
The components of the new virus actually assemble them selves through a complex process called "Self Assembly"
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 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 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 can you conclude about the surface proteins of viruses for which effective vaccines exist?
Effective vaccines usually target specific surface proteins of viruses. These surface proteins are often essential for the virus to infect host cells. By targeting these proteins, vaccines can train the immune system to recognize and fight off the virus more effectively.
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.
What are hbv proteins?
Protiens of High Biological Value (HBV) contain all the essential amino acids in the correct porportions. Proteins of HBV are usually of animal origin, One execption is soya beans which has HBV proteins. Examples of HBV proteins are: Meat, Fish, Cheese, Milk, Eggs, etc.
What are the spikes of a virus and what are the functions?
The spikes of a virus, often referred to as spike proteins, are protruding structures on the virus's surface that play a crucial role in its ability to infect host cells. These proteins facilitate the binding of the virus to specific receptors on the surface of host cells, enabling entry into the cell. Additionally, spike proteins can trigger immune responses, as they are recognized by the host's immune system, making them important targets for vaccines and therapeutic interventions. Overall, they are essential for viral attachment, entry, and immune evasion.
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.
Where does an enveloped virus synthesize its proteins?
Viral proteins are synthesized in the cytoplasm using the host's enzymes.
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.
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.
