Viruses are infectious particles. In many cases, they can cause deadly diseases. They are not part of the scheme of living things but are important in the problems they can cause. Some are useful. One type causes mottled colors in tulips.
Right at It's Roots.
No, viruses are nonliving.
viruses do replication with their DND
Since the nanotubes are very small, only some molecules can fit through them. Water is able to pass through, but the impurities in water like bacteria, metals, and viruses will not fit through. Therefore, the water will be purified through nanotubes.
non-enveloped viruses. It's naked viruses.

Viruses don't fit into the kingdoms of life because they aren't considered to be living things, even though they have DNA. Weird right?
about 500 million to 1 billion
Viruses are indicative of a greater computational biology emerging in our increasingly wired society. While often malicious in nature, viruses eventually increase the security of our information systems.
It is not in any phylum. Viruses are not living organisms, so they do not fit in the classification system we have for living creatures.
Computer viruses, Macro Viruses, and Directory Viruses
the study of viruses
Viruses use the host cells genetic material to make more of themselves. Viruses are very small (ultramicroscopic). 50 million polio viruses can fit in one human cell. Virus particles have a covering and a central core. The core contains either DNA or RNA and sometimes proteins. The covering consists of a capsid and sometimes an envelope over the capsid.
Viruses do not attack viruses.
All of these viruses like Hep A, B or C have matching proteins that work like a docking stations. They have one that fits just so with the one on the liver cell. Other viruses work the same way. The influenza virus affects the cells of the respiratory tract. Chickenpox viruses affect the skin but also the nerves.
stable viruses are very symtom, for example influenza. and viruses that are not stable, they are like animal viruses...
There are no real "Helpful Viruses". Viruses are viruses. They make things go wrong with your computer.
