  • Viruses are non-cellular organisms.
  • The name virus that means venom or poisonous fluid was given by Dmitri Ivanowsky.
  • Viruses cause diseases like mumps, smallpox, herpes, and influenza.

Explanation-

  • Viruses are mainly composed of nucleic acid and protein.
  • Nucleic acids consist of DNA and RNA.
  • The nucleic acid that is the double or single-stranded DNA or RNA forms the genetic makeup of the virus.
  • Genetic material is infectious.

Therefore the material that enters the host cell is only nucleic acid.

Additional Information

  • The protein coat called capsid made of small subunits called capsomeres protects the nucleic acid. 
  • Protein and Nucleic acid together called the nucleocapsid.
  • Viruses could be crystallized and crystals consist largely of proteins. They are inert outside their specific host cell.
