Verified step by step guidance

Understand that the lytic cycle is one of the two main types of viral replication cycles, the other being the lysogenic cycle.
In the lytic cycle, a virus infects a host cell and takes over the cell's machinery to replicate its own genetic material and produce viral proteins.
The newly synthesized viral components are assembled into new virus particles within the host cell.
Once a sufficient number of new viruses have been produced, the host cell undergoes lysis, which means it bursts open, releasing the new viruses to infect other cells.
This process results in the destruction of the host cell, which is a key characteristic of the lytic cycle, distinguishing it from the lysogenic cycle where the virus can remain dormant.
