Multiple Choice

Why is lysogeny advantageous to a bacteriophage in the context of organic chemistry?

It allows the bacteriophage to increase its mutation rate and adapt to new environments.

It provides the bacteriophage with a mechanism to avoid detection by the host's immune system.

It allows the bacteriophage to integrate its DNA into the host genome, ensuring replication with the host cell.

It enables the bacteriophage to immediately lyse the host cell and release new viral particles.

Verified step by step guidance

Understand the concept of lysogeny: Lysogeny is a process where a bacteriophage integrates its DNA into the host bacterium's genome, becoming a prophage. This allows the viral DNA to be replicated along with the host's DNA during cell division.

Consider the advantages of DNA integration: By integrating its DNA into the host genome, the bacteriophage ensures that its genetic material is replicated every time the host cell divides, without immediately destroying the host cell.

Evaluate the survival strategy: This integration allows the bacteriophage to persist in the host for extended periods, especially in environments where host cells are not abundant, thus ensuring its survival until conditions are favorable for lytic cycle activation.

Analyze the avoidance of host defenses: By remaining integrated and not producing viral particles, the bacteriophage can avoid detection by the host's immune system, which would typically target and destroy free viral particles.

Conclude the advantage: The lysogenic cycle provides a strategic advantage by allowing the bacteriophage to maintain its presence in the host population without killing the host cells, ensuring long-term survival and replication of its genetic material.
