Solution
Viruses:
- Viruses are defined as infective agents that are made up of nucleic acid molecules in a protein coat.
- Viruses are unable to replicate or multiply without utilizing the host cells' reproductive mechanisms.
- Viruses are found almost in every ecosystem on earth and these minute structures are the most abundant type of biological entity.
- Also, all living things, plants, animals, or bacteria are susceptible to viral infections.
- Viruses are made up of genetic material, ribonucleic (RNA) or deoxyribonucleic acid (DNA), which contains coded instructions for making copies of the virus, enclosed in the protective shells that are made of proteins.
- Examples are influenza virus, mumps virus, rabies virus, poliovirus, Herpes virus, human immunodeficiency virus (HIV), etc.
