In good growth conditions the bacteriophage is more likely to enter into which life cycle?

• A. Lysogenic cycle
• B. Integrative cycle
• C. Lytic cycle
• D. Subdued cycle

Answer: (C)

Verified step by step guidance

1. Understand the two main life cycles of bacteriophages: the lytic cycle and the lysogenic cycle. The lytic cycle involves the replication of the virus and destruction of the host cell, while the lysogenic cycle involves integration of the viral genome into the host genome, allowing the virus to replicate passively as the host cell divides.
2. Consider the conditions that favor each cycle. In good growth conditions, host cells are abundant and healthy, providing an ideal environment for the bacteriophage to replicate quickly and efficiently.
3. Recognize that the lytic cycle is favored in conditions where rapid replication is possible, as the bacteriophage can produce many progeny and spread to other cells.
4. Understand that the lysogenic cycle is more likely to occur in conditions where host cells are scarce or stressed, allowing the virus to persist without killing the host immediately.
5. Conclude that in good growth conditions, the bacteriophage is more likely to enter the lytic cycle, as it can take advantage of the abundant resources to replicate and spread.
