RE: Microbes Are Everywhere: You Can Run but You Can Not Hide
The virus consists of DNA or RNA surrounded by a layer of protein. Viruses are not considered living things because they can not reproduce themselves, and they are not composed of cells. What causes flu or a cold? The coughing and runny nose caused by one of the criminals is: virus. Viruses come in many forms. They are so small that they can only be seen with a very powerful microscope.
Curious, are there any "good" viruses that do helpful things (for humans)? (Also, nice posts! Very interesting)
