Compare virus and bacteria.?

Answer 1

Both bacteria and viruses have nucleic acids and proteins, reproduce using these nucleic acids, undergo transcription and translation. Some viruses have membranes too, but they don't serve the same biological functions that bacterial membranes do. Both viruses and bacteria are microscopic, and both cause disease on occasion. Both virusees and bacteria evolve rapidly compared to eukaryotes.

Bacteria have organelles, functional cellular membranes, sometimes cell walls and do their own metabolism. Viruses do not.

FYI, there are both DNA and RNA viruses.

Answer 2

Viruses are different from bacteria in that they are just a strand of RNA that attaches to cells and begins to replicate themeselves. Bacteria are unicellular organisms that feed and reproduce like normal cells. They contain DNA and RNA and are considered organsims. Because viruses don't "feed" or seek out food, just replicate, there are often debates on whether or not they are organisms.
