Study Notes
Viruses
- Viruses are infectious agents that replicate inside the cells of an organism
- They are composed of genetic material (DNA or RNA) surrounded by a protein coat
- Viruses can infect all types of life forms, including animals, plants, and bacteria
Virions
- A virion is a complete, infectious virus particle
- It consists of the viral genome and the protein coat that surrounds it
- Virions are capable of surviving outside of a host cell for a period of time
Viroids
- Viroids are small, single-stranded RNA molecules that infect plants
- They are the smallest known infectious agents, consisting of only a few hundred nucleotides
- Viroids do not have a protein coat and are not considered to be living organisms
Viruses and Viroids
- Both viruses and viroids are infectious agents that replicate inside host cells
- They are both composed of genetic material, but viruses have a protein coat while viroids do not
- Both can cause disease in infected organisms
Structure of Viruses
- The structure of a virus consists of the viral genome and the protein coat
- The protein coat is made up of repeating units of protein called capsomeres
- The shape of a virus can be helical, spherical, or complex, and is determined by the arrangement of the capsomeres
