Viruses have to attach them selves by way of a protein called a recognition factor. They bind to receptors on the host cell and then lose their capsid (coat).

How do viruses attache themselves host cells?
Viruses have to attach them selves by way of a protein called a recognition factor. They bind to receptors on the host cell and then lose their capsid (coat).
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.
Are viruses general or specific to the cells that they infect?
viruses are specific to the cells they infect called host cells
What is the part of the cell that viruses invade?
Viruses can infect animals, plants and bacteria, and the attachments vary. In animal viruses: Animal cells have a cell membrane. Viruses attach to certain proteins in that membrane. In plant viruses: Plants can also be infected with viruses. Since they have cell walls, viruses attach to those when infecting plants. In bacteriophages (viruses that infect bacteria): Special viruses called bacteriophages attach to the cell walls of bacteria by way of proteins.
What function do capsids perform?
Capsids are protein coats that protect the genetic material of a virus. They help viruses to attach to and enter host cells, as well as shield the viral genome from environmental damage. Capsids also assist in the release of the viral genetic material into host cells during infection.
What can viruses attach themselves to?
Viruses can attach themselves to host cells, bacteria, fungi, and other viruses for the purpose of infecting and replicating within these organisms. They require a specific receptor on the surface of the target cell to bind and gain entry for their replication process.
Why do viruses kill?
Your host cells in your body.
Do viruses reproduce inside host cells causing them to burst?
Yes, viruses can reproduce inside host cells by hijacking the host cell's machinery to make copies of themselves. This can cause the host cell to burst, releasing the newly formed viruses to infect other cells.
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.
Some viruses have special molecules on their capsids. what function do these molecules perform?
These molecules on the capsids of viruses can help facilitate attachment to host cells, allowing the virus to infect the cell. They may also play a role in determining host specificity and tissue tropism. Additionally, these molecules can help evade the immune system by masking the virus from detection.
Viruses can reproduce only inside what?
host cells!
Is there a difference with viruses and cells?
Yes there is a difference. Viruses are non-living and cells are living This is because Viruses can't reproduce on their own without a host. They don't have a metabolism like cells. They can't maintain homeostasis. They cannot synthesize proteins (they lack the ribosomes to do so) without a host. Without a host viruses can neither generate nor store ATP (adenosine triphosphate). Viruses cannot live unless they have a host.
