The lysogenic and lytic cycles are two distinct processes by which viruses replicate within host cells. Here’s a differentiation based on the key characteristics:

  1. Lysogenic Cycle: In this cycle, the virus integrates its DNA into the host cell's genome, becoming a prophage. The viral DNA is replicated along with the host's DNA during normal cell division, and the viral genes remain dormant until triggered to enter the lytic cycle.

  2. Lytic Cycle: In contrast, during the lytic cycle, the virus immediately takes over the host's cellular machinery to replicate its own DNA and synthesize viral proteins. This process culminates in the assembly of new viral particles and ultimately leads to the death and lysis (destruction) of the host cell, releasing the newly formed viruses.

In summary, the lysogenic cycle involves viral DNA integration and dormancy, while the lytic cycle involves active replication and cell destruction.

It looks like there was a duplication in the statements you provided. However, based on the points made about the lysogenic and lytic cycles, the best answer that captures the key difference is:

The host cell is destroyed during the lytic cycle.

This statement clearly differentiates the lytic cycle from the lysogenic cycle, where the host cell is not immediately destroyed.
