The Lytic Cycle
Captions available
The idea
In the lytic cycle, a virus replicates inside its host, assembles new virions, then bursts the cell open to release them.
In practice
Bacteriophage T4 infects E. coli, replicates quickly, and lyses the bacterium, releasing many new phage particles at once.
Where people slip
Lysis kills the host cell— a virus using only the lytic cycle cannot leave without destroying its host.
