Viruses are considered to be
a link between life and non-life
Viruses do, however, show some characteristics of living things. They are made of proteins and glycoproteins like cells are. They contain genetic information needed to produce more viruses in the form of DNA or RNA. They evolve to adapt to their hosts. they cannot replicate on their own but can do so in truly living cells and can also affect the behavior of their hosts profoundly. Hence viruses are considered as the link between living and non-living
