accelular microorganisms (viruses, viroid and prions)

4. viral structures

Caspid (protein coat) ~icosahedral ~pleomorphic ~cylindrical

Envelope (covered caspid) ~lipid ~protein ~carbohydrates

Nucleic Acids ~DNA or RNA ~ss or ds DNA ~segmentation ~sense of the strand

3. size

~smaller than bacteria ~wide range

2. host rrange

~infect inveterbrate, vetebrate, plant, protist, fungi, bacteria ~narrow host range ~specific host

5. classification

using International Commities for Taxonomy o virus(ICTV) ~ nucleic acid type ~ nucleic acid strandedness ~the sense (+ve/-ve) of ssRNA ~presence?absence of envelope ~type of host

6. morphology

~helical viruses ~polyhedral viruses ~enveloped viruses ~complex viruses

1.general characteristic

~smaller than bacteria ~must have host to survive ~contain a single nucleic acid ~contain a protein coat
