Document Summary

Lecture 17- biology of viruses virion capsids complete virus particle consists of 1 molecule of dna or rna enclosed in coat of protein cannot reproduce independent of living cells nor carry out cell division but can exist extracellularly. Large macromolecular structures which serve as protein coat of virus. Protect viral genetic material and aids in its transfer between host cells. Capsids are helical, icosahedral (12 edges, 20 sides), or complex helical capsids. In helical viruses, a single protomer forms the entire capsid. Can be either rigid (tmv) or flexible (influenza) Virion size is a function of genome size virus morphology. Can be naked (non-enveloped) or have lipid envelope surrounding the nucleocapsid. Composed of a nucleic acid-encoded (rna or dna) genome and a proteinaceous coat or capsid viral envelopes. Viral envelopes are derived from the lipids of the host cell with virally-encoded proteins present. Viral spike proteins are often used for attachment to host cells.
