Which of the Following is Most Similar to Lysogeny

Question

Which of the following is most similar to lysogeny?
A) Hfr state
B) F⁺ state
C) F⁻ state
D) Fʹ state

Accepted Answer

Lysogeny is the process by which a viral genome integrates into the host bacterial genome and is replicated along with it. The Hfr (high frequency of recombination) state is also a type of integration of the F factor (a plasmid) into the bacterial genome, resulting in transmission of chromosomal genes across bacterial cells. Therefore, the Hfr state is most similar to lysogeny. The F⁺, F⁻, and Fʹ states are all related to the transfer of the F factor but do not involve integration into the bacterial genome.
