Study Notes
Virus Characteristics
- Viruses multiply by taking over the host cell's machinery to replicate themselves.
Sensitivity to Antibiotics
- Viruses are insensitive to antibacterial antibiotics, unlike prokaryotes.
Viral Structure
- A virus' capsid is composed of proteins that protect the viral genome.
- The capsid is made up of repetitive subunits of proteins.
Size of Viruses
- The size of viruses is estimated using electron microscopy or filtration methods.
- The size of the smallest parvovirus is comparable to the size of the largest protein molecule, haemocyanin.
Cellular Organization
- Viruses lack cellular organization and are not considered living cells.
Multiplication Method
- Viruses multiply by infecting host cells, replicating their genome, and assembling new virions.
Discovery
- Wendell Stanley crystallized virus-like chemicals in 1935, showing that viruses have a crystalline structure.
Disease Range
- Viruses cause a wide range of diseases, including common colds, influenza, and serious diseases like AIDS and Ebola.
