A. The reproductive cycle of this virus is likely the lytic cycle, as it causes rapid symptoms within a short period of time (3-5 days).
B. Major differences between the lytic and lysogenic cycles include:
1. Lytic Cycle:
- The viral DNA enters the host cell and immediately takes control of the cellular machinery.
- The viral DNA directs host cell to produce new viral components, such as viral proteins and genetic material.
- These components assemble to form new viruses.
- The host cell lyses (bursts), releasing the newly formed viruses to infect other cells.
- The lytic cycle results in immediate cell death and the virus spreads quickly.
2. Lysogenic Cycle:
- The viral DNA integrates into the host cell's DNA, becoming a part of the host genome.
- The viral DNA is replicated along with the host cell's DNA during cell division.
- The viral DNA remains in a dormant state, not producing new viral particles.
- In certain conditions or due to environmental triggers, the viral DNA can be activated to undergo the lytic cycle.
- The lysogenic cycle allows the virus to persist within the host cell for long periods without causing immediate cell death.
