A viruses is a small structure that has a protein coat with a pieces of genetic material. It invades the cell of its host and uses the hosts DNA to replicate its own genetic material. Once the cell has replicated the viruses DNA the cell ruptures and the viral DNA is sent throughout the hosts body. A virus is not technically classified as a living thing. It is not able to replicate and reproduce with out a host.
A bacteria is classified as a living thing. It is a prokaryotic organism with the ability to reproduce using its own genetic material DNA/ RNA.
How are bacteria, viruses and cells similar and different?
Viruses are not made of cells while bacteria is.
Reply:They r all very small.Viruses and bacteria r living things like animals. Cells r what make up every living thing. Viruses have a nucleus and Bacteria don't.
Reply:Bacteria are larger than viruses, bacteria are alive (viruses are like these hijacking robots), bacteria can't make their own stuff (or reproduce) that's why they hijack other cells to do make stuff for them.
Bacteria has organelles and membranes and all that stuff, viruses only have a protein coat and a DNA or RNA inside them.
Reply:all are very small but viruses are protists, while bacteria can survive and replicate on their own
