Virus is Latin word which means "POISON". They are of different shapes, some are rounded, rod-shaped, and polyhedral and some are like tadpoles. STRUCTURE:Structurally viruses are not cellular but are made up of nucleic acid and proteins. They have to parts, an outer "coat" and inner "core". The coat is made up of proteins and core is made up of DNA or RNA. AWAIS AHMED awais94_2005@Yahoo.com Pakistan INTERNATIONAL SCHOOL JEDDAH
Viruses are very complexed 'things'. I call them things because although they are technically alive, the show none of the signs of the life.
A virus is basically a ball of protein which encases the viruses strand of RNA or DNA. On the surface of a virus is its antigens which act as identification. (these are how the immune system recognises them as foreign)
A virus reproduces by taking of a cell of the host organism, injecting its DNA or RNA strand which overrides the hosts, and basically turning the cell into a virus making factory. The viruses DNA tells the cell to create virus cell after virus cell until the viruses burst out of the cell and invade others around the body.

The capsid of the cell helps the virus to infect host cells as well as multiply quickly.

A virus is debatably not a living thing, it stores no energy and "tricks" the cell into expending its own energy which the virus then uses for its "evil deeds"
A virus has no cell structure, but it has genes :)

The disease that come from a virus.
a typical virus has a core of DNA or RNA and a protein coat
If you use balls to explain the structure of a molecule you have made a model.
A helical virus has a spiraling structure similar to a spiral staircase. The virus genome is arranged in the middle of the spiral staircase. The Tobacco mosaic virus is a helical virus.
Yes. It is either DNA or RNA.

Fixing a boot up structure that is corrupted due to a virus can be difficult to deal with depending on the extent of the damage done. Reformatting the hard will can fix the boot up structure. If the virus destroys the Master Boot Record then the hard drive is useless paper weight.
