The Intricacies of Viral Architecture
Viruses are fascinating entities that occupy the gray area between life and non-life. Their structure is both simple and incredibly complex.
Basic Components
- Nucleic Acid: Either DNA or RNA, which carries genetic information.
- Capsid: A protein shell that encases the nucleic acids.
- Envelope: Some viruses have a lipid membrane derived from the host cell.
Shapes of Viruses
Viruses come in a variety of shapes that relate to their method of infection:
- Icosahedral
- Helical
- Complex
