MCRO 251 Lecture Notes - Lecture 6: Capsomere, Provirus, Veterinary Virology
Document Summary
Viral spikes force the cell to take it in. Viral spikes and ligand on the cell it infects. Release capsomere in cytoplasm and release genetic material. When a virus is in the cell there is no real way to get rid of it, we have to kill the cell. Envelope virus - smooth plasma membrane with spikes, lipid layer is fused into the membrane of the cell membrane, attachment absorbtion, virus comes in and uses our stuff (ribosomes, etc. ) Naked viruses lyse the cell, they utilize all of the cells energy and weaken it until it ruptures. Enveloped viruses has to come from the living cell, insert viral spikes into the cell membrane, this is how animal viruses replicate. Burst time (release 500 more in 45 mins) phage particles released by lysis. We need to identify them before they take over. Acute infection (influenza) (24-36 hours) virus disappears after disease ends.
