No. Being that viruses are not a living organism, they are neither contain cells, nor are they a cell themselves. Viruses are merely few macromolecules (such as nucleic acid and protein) which combines to form a pathogenic particle.dit: a cell wall-as the name implies-is a part of a cell. Viruses are not cells. â¦ Cells are living, viruses are not.
The illustration at left depicts a virion â the infectious particle that is designed for transmission of the nucleic acid genome among hosts or host cells. A virion is not the same as a virus. I define virus as a distinct biological entity with five different characteristics.Others believe that the virus is actually the infected host cell. The idea that virus and virion are distinct was first proposed by Bandea in 1983.ow about a virus is: the genetic material, and a virion is the vehicle that transports it, a cell with virus particles is simply a cell infected with a virus. The thing is, science and academics are not supposed to be easy, they are just what they are.
