Antivirals are much less effective you have to kill host cells. 1 adsorption virus sticks to viral receptor on host cell. 2 penetration virus enters the cells. 3 uncoating protein coat stripped, dna / rna is free. 4 replication uses host cell mechanisms to copy. 5 assembly uses host cell ribosomes to make proteins to make more viruses. Type 1: replicate until there are so many viruses the host cell bursts. Virus pushes out of host, taking membrane with it. When an enveloped virus attaches to the host, the envelope fuses with the host"s cell membrane. Enveloped viruses do not last long outside of host cells. The envelope is essential to its function and it denatures quickly.
