A complete virus particle is called virion consisting of its simple nucleic acid (either RNA or DNA) and a protein coat called capsid. Viruses with DNA as genetic material are called DNA virus ( eg: herpes virus or Adenovirus etc) and those with RNA as genetic material are called RNA viruses ( e.g.: Foot and Mouth disease virus, SARS virus, HIV etc).
