Can viruses cause mutations?
It is not believed so, but viruses are able to infect cells and replace the cell's DNA "instructions" with the virus' DNA or RNA instructions. This is how they reproduce using a host's cells to do the work. There is some thought in the scientific research areas that one day we may be able to do gene therapy using viruses to implant the correction into the target cell types, but not yet. Viruses themselves can mutate into new forms, however, and this may be what you are thinking of. The viruses are able to change the proteins in their capsid (coat) and make new viruses through this mutation that no longer get attacked by our immune systems. Our bodies no longer recognize them as the same with the different protein composition and our immune defenses that were developed against the original version of the virus won't work any more until our bodies develop new antibodies for the mutated strain of virus.
Can a virus infect any type of cell?
Yes.It infects fungi,plants,animals and bacterias
ARE Viruses are a type of cell?
The type of cells that viruses live in are host cells. Viruses need host cells in order to reproduce or multiply.
Where did viruses come form?
Answer -------Tracing the origins of viruses is difficult because they don't leave fossils and because of the tricks they use to make copies of themselves within the cells they've invaded. Some viruses even have the ability to stitch their own genes into those of the cells they infect, which means studying their ancestry requires untangling it from the history of their hosts and other organisms. What makes the process even more complicated is that viruses don't just infect humans; they can infect basically any organism-from bacteria to horses; seaweed to people.Still, scientists have been able to piece together some viral histories, based on the fact that the genes of many viruses-such as those that cause herpes and mono-seem to share some properties with cells' own genes. This could suggest that they started as big bits of cellular DNA and then became independent-or that these viruses came along very early in evolution, and some of their DNA stuck around in cells' genomes. The fact that some viruses that infect humans share structural features with viruses that infect bacteria could mean that all of these viruses have a common origin, dating back several billion years. This highlights another problem with tracing virus origins: most modern viruses seem to be a patchwork of bits that come from different sources-a sort of "mix and match" approach to building an organism.The fact that viruses like the deadly Ebola and Marburg viruses, as well as the distantly related viruses that cause measles and rabies, are only found in a limited number of species suggests that those viruses are relatively new-after all, those organisms came along somewhat recently in evolutionary time. Many of these "new" viruses likely originated in insects many million years ago and at some point in evolution developed the ability to infect other species-probably as insects interacted with or fed from them.
What is the scientific proof that viruses are not living organisms?
Viruses lack any form of energy and are not alive according to this definition. Computer viruses make slight changes in their code (mutate) but they are not alive. Computer viruses can mutate to overcome antiviral software but they are not considered to be alive anymore than what we call viruses that infect microorganisms or host cells.
What do viruses that cause physical diseases infect?
It depends on what kind of virus. Viruses can infect any cell in the human body. Viruses such as HIV infect the immune system; air-born viruses, such as H1N1 or a cold, infect the respiratory system; neurological viruses, like rabies infect the brain (the virus is usually carried to it by peripheral nerves); and viruses like polio effect the nervous system, which can create paralysis.
Are viruses devoid of any biochemical machinery and thus behave like dead particles inside the cell?
viruses behave like dead particles out of the cell and in specific out its particular cell. Once inside its cell, the virus uses the cell's machinery to "come alive" it then begins to reproduce and infect other of the same type of cell.
What is a pandoravirus?
A pandoravirus is any of a species of very large viruses which infect amoebas.
Is there any specific name for a helpful virus?
No. Any and all viruses are parasitic. There may not be any helpful viruses, but there are certainly a large quantity of harmless viruses, which doesn't infect humans, but rather specific animals or plants.

Yes.It infects fungi,plants,animals and bacterias
Are computer viruses alive and why or why not?
Computer viruses aren't living things. These are pieces of mal-ware created by humans to infect computers with infectiousness software. They cannot harm you in any way, but can destroy a computer.
