Question

A virus cannot reproduce on its own. Viral DNA or RNA must enter the host cell and direct the cell to make the materials needed to produce more viral particles. There are two pathways a virus may take: the lytic or lysogenic pathway.

How are the lytic and lysogenic viral pathways ALIKE?
A) They both have a prolonged period of dormancy.
B) They both eventually cause the death of the host cell.
C) In both cases, viral DNA is replicated when the host cell undergoes fission.
D) In both cases, viral DNA is integrated into the host DNA for a period of time.

Answer 1

In both cases, viral DNA is integrated into the host DNA for a period of time

Answer 2

B) They both eventually cause death of the host.

Step-by-step explanation:

Viruses do not have their own energy producing system. Thus, viruses can only reproduce or replicate using host energy and reproduce by two methods. These are called the lytic cycle and the lysogenic cycle. In both the cycles, the viruses inject their genetic material into the host cell. In the lysogenic cycle, the viral DNA is integrated into the host DNA, while in the lytic cycle, the viral DNA exists as a separate free floating molecule within the host cell, and it reproduces separately from the host DNA. In both the cases the host cell die.
