Study Notes
Fungi Classification
- Ascomycota includes common antibiotic-producing fungi and yeasts
- Imperfect fungi (Deuteromycota) do not produce sexual spores and reproduce asexually
- Zygomycota is known for producing respiratory and systemic infections
- Zygomycota is commonly known as bread molds
- Basidiomycota includes mushrooms, toadstools, rusts, and smuts
Virus Characteristics
- Viruses are not considered living cells, so they do not carry out metabolic processes
- The host range of a virus is determined by the type of protein on the surface of the viral capsid
- Viruses are classified based on their capsid symmetry, genome type, and host range
- The protein coat (capsid) is responsible for the infectivity of viruses
- The specific shape of the viral protein coat determines the host cell receptor specificity
