Virus Dissemination

I will be researching Ebola virus, and I will investigate in depth on this virus. As we saw in the CellsAlive Interactive the Ebola virus is a 100,000 times zoom for the human eye to see it. To start I will go in depth of exactly what a virus is and how it spreads. A virus is a tiny particle, virus particles are about one-millionth of an inch (17 to 300 nanometers) long. Viruses are about a thousand times smaller than bacteria, and bacteria are much smaller than most human cells. Viruses are so small...

The Ebola Virus A virus is an ultramicroscopic infectious organism that, having no independent metabolic activity, can replicate only within a cell of another host organism. A virus consists of a core of nucleic acid, either RNA or DNA, surrounded by a coating of antigenic protein and sometimes a lipid layer surrounds it as well. The virus provides the genetic code for replication, and the host cell provides the necessary energy and raw materials. There are more than 200 viruses that...
