The diagram models the lytic and lysogenic reproductive cycles of virusesWhich cycle would maintain the DNA of the virus over several generations and why?A. Lytic, because the viral DNA can be exised from the host cell's DNA when under stress.B. Lytic, because the viral DNA can be passed on when the host cell replicates.C. Lysogenic, because the viral DNA can be excised from the host cell's DNA when under stress.D. Lysogenic, because the viral DNA can be passed on when the host cell replicates.
Question
The diagram models the lytic and lysogenic reproductive cycles of virusesWhich cycle would maintain the DNA of the virus over several generations and why?A. Lytic, because the viral DNA can be exised from the host cell's DNA when under stress.B. Lytic, because the viral DNA can be passed on when the host cell replicates.C. Lysogenic, because the viral DNA can be excised from the host cell's DNA when under stress.D. Lysogenic, because the viral DNA can be passed on when the host cell replicates.
Solution
The cycle that would maintain the DNA of the virus over several generations is the Lysogenic cycle. This is because in the Lysogenic cycle, the viral DNA is integrated into the host cell's DNA and is replicated along with the host cell's DNA when it replicates. Therefore, the viral DNA is passed on to the daughter cells during cell division. In contrast, in the Lytic cycle, the viral DNA is not maintained over several generations as it is not integrated into the host cell's DNA and is instead replicated separately.
