There are several key differences between the lysogenic and lytic cycles:
Lytic Cycle:
1. In the lytic cycle, the host cell is immediately infected by the virus and its replication machinery is used to produce viral components.
2. The virus injects its genetic material (DNA or RNA) into the host cell.
3. The viral DNA takes control of the host cell's machinery, leading to the production of viral components.
4. The host cell is eventually destroyed when numerous viral particles are released, rupturing the cell.
Lysogenic Cycle:
1. In the lysogenic cycle, the virus integrates its genetic material into the host cell's DNA, becoming part of the cell's genome.
2. The viral DNA is not immediately active, and the host cell continues with its normal functioning.
3. During latency, the viral DNA can be copied and passed on to daughter cells when the host cell divides.
4. Under certain conditions (e.g., stress or environmental cues), the viral DNA can re-enter the lytic cycle, leading to the destruction of the host cell and the release of viral particles.
To sum up, the main distinctions lie in the immediate destruction of the host cell in the lytic cycle, the injection of viral DNA into the host cell, and the viral proteins synthesis. Conversely, the lysogenic cycle involves the integration of viral DNA into the host's genome and latency in which the viral DNA can be passed on to daughter cells.
differentiate between the lysogenic and lytic cycles
the host cell copies its own dna during the lytic cycle
the virus injects dna into the host cell during the lysogenic cycle
the host cell is destroyed during the lytic cycle
viral proteins are synthesized during the lysogenic cycle
