list at least 5 major differences between bacteria and viruses Solution Bacteria 1. Contains both DNA and RNA, of which DNA is inherited and 2. Do not need a host to replicate. Can grow on any appropriate nutrient medium . 3. Size ranges in 0.2 - 2 micrometer in diameter and 0.5 - 5 micrometers in length. 4. Their structure consists of cell wall, plasma membrane, ribosome, and sometimes flagellum and inclusion bodies. 5. They grow by cell division and replication. Viruses 1. Contains either DNA or RNA as genetic material but not both. 2. Can produce only within living cells, need a host to replicate. 3. Size ranges 0.02- 0.3 micrometer 4. Structure consists of a protein coat, surrounded on the nuclei acid, collar, sheath, tail fibres and tail pins. 5. Reproduce by either lyric or lysogenic cycle..
