Viruses are arranged quite simply. Individual virus particles – virions – consist of nucleic acids and proteins. The genetic apparatus of viruses can be represented by a DNA or RNA molecule. Nucleic acid is the core of the virus and is protected by a protein shell called a capsid, moreover, it can be wrapped in a capsid spirally or rolled up into a ball. The virus capsid is built from many protein subunits and, depending on their location, has a different configuration. Diseases that cause viruses: Herpes, influenza, HIV, polio.
