Host specificity of a virus can be attributed to a few different factors. One of these factors is a viral species ability to "hijack" a cells internal machinery and cause it to reproduce the genetic makeup and proteins which make it up. Many viruses then exit the cell (usually through destroying it) and may take a part of the cell's membrane with them as a sort of phospholipid coat. This membrane has all of the identifying proteins which enable our cells to recognize one another and serves viruses in the same manner.

Does the host cell usually benefit from having a virus?
The host cell does not benefit from having a virus. The virus usually kills it.
What is a virus called outside a host cell?
A virus outside a host cell is generally referred to as a virion. This is the inactive form of the virus that is unable to replicate until it enters a suitable host cell.
Why is it difficult to target a pathogenic virus without damaging the host's cell?
One of the gud example is HIV virus because genetic material of the virus incorporated into the host genetic material and suppress the host metabolic activity it make strength resemble to host .if we can use drugs against virus it doesnt identify different btwn host and virus.so that drugs cause side effects in host .
Does a virus need a crystal or a host to reproduce?
A virus does not need a crystal to reproduce, as they are not living organisms and do not have cellular machinery to perform reproduction. However, a virus does need a host cell to replicate and produce new virus particles.
What is a host cell for a virus?
A host cell for a virus is a cell that the virus can infect and hijack to replicate itself. The virus enters the host cell, takes over its machinery to produce more virus particles, and then spreads to infect other cells.
What does virus specificity mean?
Virus specificity refers to the ability of a virus to infect specific host cells or organisms due to interactions between viral and host cell surface molecules. Each virus has a specific range of hosts that it can infect based on these molecular interactions, which determine its infectivity and pathogenicity. This specificity is what underlies the diverse range of diseases caused by different viruses.
What is viral specificity?
Viruses are highly specific and can only attack particular cells of a particular organism. Ex. Polio virus attacks nerve cells Mumps virus attacks salivary glands Hepatitis virus attacks liver cells
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.
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.
What is the collar function in virus?
The collar function in a virus helps the virus attach to host cells by recognizing specific receptors on the cell surface. This attachment is necessary for the virus to enter the host cell and infect it. The collar function can vary between different types of viruses and plays a crucial role in determining host specificity.
Are viruses host specific?
It means that a virus will only attack what its meant to. ie: If you get the flu the virus is supposed to attack your airways that is why you get a stuffy nose and a cough if it was not specific it would mean that you could catch the flu virus and get a pain in your leg. it means that a virus can infect to its specific host only which provides it suitable environmernt to replicate. the infection needs host and virus surface interactions and also the genetic compatebility a virus which may infect a plant or animal may not infect humans due to its host specificity but when there occurs a barrier crossage b/w any two species due to mutations or genetical adaptations etc by a viral genome then the virus gets the potential to infect unusual or new hosts and results in new viral strains for eg. the case of HIV and H1N1 can be stdied for this, and this is the case of modified host specificty.
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.
Can a virus have a host?
Viruses do not cause diseases in the host. Why? Well, the host is already causing the virus so it is IMPOSSIBLE for another virus to be cause in the host.
What is the first event that occurred when a virus infects the host cell?
The virus attaches to the host cells membrane.
Why isn't virus in the taxonomic system?
The virus isn't in the taxonomic system because there is an ongoing debate between many people on whether or not the virus is actually living or not, due to the fact that the virus has to rely on a host to reproduce.
The cell infected by a virus is referred to as the?
The cell infected by a virus is referred to as the host cell. The virus hijacks the host cell's machinery to replicate and produce more virus particles.
What is a process that a virus can do in a host?
First the virus enters the host cell, then the virus' hereditary material come, then the host cells hereditary material becomes viral, then the host cell expands, and then it POPS!!!
