Viral structure and reproduction
10 October 2022 10:40
Structure of a virus
- Acellular (particles), non-living
- 20-300nm in size
- Nucleic acids such as DNA or RNA are genetic material - enclosed within a protein coat
capsid
- Some viruses have a lipid envelope
- Lipid envelope or capsid have attachment proteins which allow the viruses to attach to
- No plasma membrane, cytoplasm, ribosomes
Ie bacteriophage (virus that only infects bacteria) structure:
- Mutations more likely in viruses who have RNA than DNA
