Attachment - They bond to our cells by a specific port of entry.
Penetration - They penetrate our cells by phagocytosis (our cell pulling it in)
Enveloped viruses can also pentetrate cell by fusion, when the envelope fuses to cell membrane.
Uncoated - when the viral nucleic acid is seperated from its protein coat.
Replication (biosynthesis) - making more viruses. Viruses Can replicate it (cytoplams, nucleoplasm or chromosome)
- Release - budding, lysis (the cell is destroyed) or
- latency (provirus, when a virus gets in out cell's chromosome and never leaves, everytime we reproduce celsl it will have the virus in the chromosomes)
