Viruses attach to living cells by binding to the cell receptors. The receptor site is very much like a jig-saw puzzle and the virus must be shaped to fit the site and to lock in. The virus first sticks to the cell membrane of the host cell. The virus then inserts its DNA/RNA into the cell's cytoplasm. Once inside the host cell, the virus is uncoated, i.e. its capsid is dispersed, exposing the DNA/RNA. The DNA/RNA then takes over the host cell. The virus makes the cell produce new viral DNA/RNA and new capsomeres (proteins make up the capsid). The nucleic acid and the capsomeres are assembled in the cell to make new virus particles which escape from the cell. The cell might lyse and release new viruses to infect other cells.
Examples of viral infection are cold sore, measles and chicken pox.

How do some viruses trick cells into letting them in?
How do some voruses trick cells into letting them in
How do you explain how copies of viruses are produced?
copies of viruses are produced because some viruses stay inside there host cells.
Viruses are living organisms?
viruses are not living organisms. They simply attach to a cell and when the cell reproduduces the virus is reproduced with the new cells.
How do viruses infect people?
When a typical virus infects a host cell, the latter ultimately dies. The virus first enters the host cell and then uses the cell's organelles to replicate itself. Eventually the host cell ruptures, spilling new viruses into the host's bloodstream. However, there are some viruses that don't kill their host cells.
What infectious agent live only by invading cells?
strict pathogens like Spirochetes only can live in host due there short genome
How do viruses attach themselvs to 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).
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).
Some viruses have special molecules on their capsids. what function do these molecules perform?
Molecules preform a few functions. The most important function is to layer the cells.
Are viruses general or specific to the cells that they infect?
viruses are specific to the cells they infect called host 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.
Why do viruses kill?
Your host cells in your body.
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.
How do some viruses trick cells into letting them in?
How do some voruses trick cells into letting them in
Viruses can reproduce only inside what?
host cells!
What is a host cell for a virus?
Host cells of viruses include human and other animals, and plants and fungi. Also bacteria and protozoa and algae are host cells of viruses.
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.
Why do viruses depend in host cells?
Viruses are composed of protein and DNA. The DNA encodes the protein as well as the DNA for the virus. Viruses depend on host cells because they are incapable of reproducing themselves. They enter the host cell and the viral DNA is inserted into the host DNA. The virus then "hijacks" the host cells replication machinery to make more viral protein and viral DNA.
