Detailed explanation-1: -Viruses are biological structures that have a nucleic acid genome surrounded by protein and lipids. They have no nucleus, no ribosomes, and none of the membrane bound organelles.
Detailed explanation-2: -Viruses are responsible for a wide range of diseases, including the common cold, measles, chicken pox, genital herpes, and influenza. Many of the emerging infectious diseases, such as AIDS and SARS, are caused by viruses.
Detailed explanation-3: -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.
