Detailed explanation-1: -The lytic cycle: The phage infects a bacterium, hijacks the bacterium to make lots of phages, and then kills the cell by making it explode (lyse).
Detailed explanation-2: -The lytic cycle (/ˈlɪtɪk/ LIT-ik) is one of the two cycles of viral reproduction (referring to bacterial viruses or bacteriophages), the other being the lysogenic cycle. The lytic cycle results in the destruction of the infected cell and its membrane.
Detailed explanation-3: -The difference between lysogenic and lytic cycles is that, in lysogenic cycles, the spread of the viral DNA occurs through the usual prokaryotic reproduction, whereas a lytic cycle is more immediate in that it results in many copies of the virus being created very quickly and the cell is destroyed.
Detailed explanation-4: -In which step of the lytic cycle is the host cell destroyed? The host cell is destroyed during lysis, during the last step.
