a complete virus particle
viruses which infect prokaryotes
size range of virus
shapes of viruses
helical, isometric and complex
purpose of capsid
protect nucleic acid
steps to animal virus replication
Penetration and Uncoating
fusion vs endocytosis
fusion: Happens in enveloped virus. Binds with receptors and the envelope of virus fuses with the membrane of the cell. the virus is then taken in. Envelope stays with membrane and nucleic acid separate from capside in the cytoplasm
endocytosis: Happens in non enveloped viruses. After it binds with receptors, the membrane of the cell surround the virus and take it in.
chronic vs latent
chronic produces low levels of viroids while latent is completely in activated
how does a virus work in latent infections?
integrates permanently in the chromosome
are small single-stranded RNA molecules
type of virus which uses oral fecal route
all naked viruses have nucleocapsid T or F
makes them more resistant to ??
