<h3>What are viruses?</h3>
Viruses are microscopic non-cellular structure consisting of a core of DNA or RNA (nucleic acid) surrounded by a protein coat (capsid). 
A virus is considered as by non-living because it requires a living host cell to replicate, and often causes disease in the host organism.
Therefore, the characteristics that apply to viruses are;
- Viruses are made of RNA or DNA.
- Viruses have a protein coat
