The bacteriophage incorporates into the host genome in which phase?
Correct answer: A. Lysogenic cycle
- A. Lysogenic cycle
- B. Lytic cycle
- C. Both
- D. None of the above
Explanation
The bacteriophage incorporates into the host genome in the lysogenic cycle. In the lysogenic cycle, the bacteriophage DNA integrates into the host DNA and becomes a prophage. The prophage is then replicated along with the host DNA and is passed on to daughter cells when the host cell divides. The prophage can remain dormant in the host cell for many generations, or it can be triggered to enter the lytic cycle and produce new phages.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
