Current Deck: MICR3320::02. virus replication
PublishedCurrently Published Content
Front
viral components synthesised during an infection
Back
- after virus attaches to its host cell, viral genome enters cell and eclipse phase begins
- cell fills with viral mRNA, cellular mRNA synthesis may completely shut off within a few mins
- as viral mRNA increases, so do levels of viral proteins needed for gene expression and genome replication
- next, viral genomes begin to accumulate and capsomeres are synthesised
- just before lysos, cell fills with intracellular virions which have assembled from their component parts
