What is a virus ?how do vireses differ from bacteria? |

Answer» Explanation: A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. VIRUSES can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. Bacteria and viruses differ in their structure and their response to medications. Bacteria are single-celled, living organisms. They have a cell wall and all the components necessary to survive and reproduce, although some may derive energy from other sources. Viruses are not considered to be “living” because they require a host cell to survive long-term, for energy, and to reproduce. Viruses consist of only one piece of genetic material and a PROTEIN shell called a CAPSID. They survive and reproduce by “hijacking” a host cell, and using its RIBOSOMES to make new viral PROTEINS. |
