The virus injects DNA into the host cell during the lysogenic cycle.

The main difference between the lysogenic and lytic cycles is the ultimate outcome for the host cell.

In the lysogenic cycle, the virus injects its DNA into the host cell but does not immediately take over and destroy the host cell. Instead, the viral DNA becomes integrated into the host cell's DNA and is replicated along with the host cell's DNA when the host cell divides. During the lysogenic cycle, viral proteins are not actively synthesized. The viral DNA may remain dormant within the host cell for an extended period of time.

In contrast, during the lytic cycle, the virus immediately takes over the host cell's machinery to replicate its own viral components. The host cell is used to produce new viral particles, which are then released when the host cell is lysed or ruptured. The host cell is ultimately destroyed in the lytic cycle. Additionally, during the lytic cycle, the host cell copies its own DNA as part of its normal cell division process.
