Can viruses carry out any of the characteristics of life on their own?
No, because viruses cannot carry out life processes without a host organism.
Viruses share a few characteristics with living organisms but not many, viruses are essentially just chains of proteins. They contain genetic information but they do not have any cellular stucture as most other forms of life do. The average virus about one one-hundredth the size of the average bacterium and viruses do not have their own metabolism but require a host cell.
Viruses do not belong to any kingdom and don't contain any cells. Therefore, they are considered nonliving. In addition, viruses do not have the characteristics of life. It cannot respond to a stimulus. It cannot grow and develop. It cannot adapt to the environment. The only way to reproduce is to do it inside a host cell and cannot independently reproduce.
Viruses are not living because they do not exchange any gasses, they do not require any life-sustaining nutrients, and they do not reproduce on their own. A virus is a small particle that contains a small portion of DNA. It must attach to a living cell and transfer its DNA in order to reproduce. The cell then takes on similar characteristics of the virus.
