The most basic viruses are composed of either RNA or DNA and are surrounded by a layer of protein subunits. Some viruses have a viral envelope that serves to protect the virus from the immune system and helps with adhesion of a virus to other things. The complex viruses consist of an icosahedral head attached to a helical tail often attached to protein fibers that can look like 'legs'.

Do all viruses kill you?
If that were true, we would all be dead from having colds, which are caused by viruses. The reality is many viruses are harmless or just an inconvenient if you are otherwise healthy.
Causes of computer viruses?
Programmers
Why weren't viruses discovered until about 1935?
The very small size of virus particles was a major limiting factor of the discovery of viruses.
What is first virus name in computer?
some viruses can come from LIME WIRE. because of some of the musics you download may have viruses.
Where would a medical researcher obtain viruses for experiments?
Places like the Centers for Disease Control (CDC) have viruses preserved in special containers for just such purposes.
Are viruses made up of tissues?
No, tissues are made up of cells and viruses are not even cells.
What are substances made from weakened viruses or bacteria?
Inoculations (for immunization) are substances made from weakened viruses or bacteria.
What are substances made from dead viruses?
Vaccines for the prevention of the specific viral infection can be made with inactive "dead" viruses. They are also made with live, but attenuated (weakened), viruses. See more below about vaccines.
Are all viruses made out of a cell or cells?
Viruses are made of nucleic acids; some also have a protein shell.
Why viruses are difficult to classify as living organisms?
It is because viruses are not made up of cells
Are the microbes that are injected in a vaccination dead or alive?
They can be either. Some vaccines are made with dead viruses or particles of viruses and other vaccines are made with attenuated (weakened) viruses that are not able to make an otherwise healthy person sick. In 2009 the swine flu vaccine approved for use in the US was prepared both ways, the nasal flu vaccine was made from attenuated viruses and the shots were made with dead viruses.
Why they are telling that virus is made up of cell?
They are confused of what are viruses (or they discovered something we don't know), but importantly viruses are not made out of cells or a cell
What is injection of weakened viruses is called?
A vaccination using a vaccine made from attenuated live viruses.
What are vaccines for influenza made from parts or products of a virus dead whole viruses antibodies to the virus weakened viruses?
What are vaccines for influenza made from?parts or products of a virusdead, whole virusesantibodies to the virusweakened viruses
What are solutions of killed or weakened viruses?
One such example would be a vaccine for viral illnesses. They can be made from attenuated (weakened) viruses or from inactivated viruses or pieces of them.
Does cells have viruses?
cells are not made with viruses unless the virus gets into the cell itself. The viruses get into the cell and the virus will spread killing off whatever it can ;)
Do viruses have a mitocondria?
No- viruses are acellular, which means that they are not made up of groups of cells, and thus do not have mitochondria present in them.
