When the phage nucleic acid is incorporated into the nucleic acid of its host and is Replicated when the host DNA is replicated, this is considered part of which cycle?
Lytic cycle
Virulence cycle
Lysogenic cycle
Cell cycle
The Correct Answer is C
A. Lytic cycle: In the lytic cycle the phage takes over, replicates separately, and lyses the host -it does not integrate into host DNA.
B. Virulence cycle: Not a standard term for integration; usually refers to virulent (lytic) behaviour.
C. Lysogenic cycle: In the lysogenic cycle the phage genome integrates into the host chromosome as a prophage and is replicated with host DNA.
D. Cell cycle: Refers to host cell division processes, not the phage integration process.

Correct Answer is {"dropdown-group-1":"A"}
Explanation
A. Identification: Biomedical (biochemical) tests are used to identify microorganisms by their metabolic, enzymatic, or physiological properties.
B. Inspection: Inspection is a general observational step but does not describe the use of biochemical identification tests.
C. Isolation: Isolation involves separating a pure culture (e.g., streak plate) prior to performing identification tests.
D. Incubation: Incubation is the process of providing time and temperature for growth; biochemical tests are applied after or during identification workflows.
