Question

Which best describes the lytic and lysogenic cycles?

Unlike the lytic cycle, the lysogenic cycle involves production of virus particles.
Unlike the lysogenic cycle, the lytic cycle involves destruction of the host.
Symptoms of infection appear in the lysogenic cycle but not in the lytic cycle.
For virulent viruses, the lysogenic cycle is the main way of replicating.

Answer 1

The answer is: Unlike the lysogenic cycle, the lytic cycle involves destruction of the host.

In the lysogenic cycle a virus does not kill the host. Regarding the other statements, in the lytic cycle symptoms of infection appear, and, also, it is the main way of replicating virulent viruses.

Answer 2

Answer: Unlike the lysogenic cycle, the lytic cycle involves destruction of the host

Lysogenic cycle is a method by which virus can replicate its DNA using the host cell mechanism. During this phase bacteria integrate its DNA in to host cell to make viral copy to infect the organism.

The lytic cycle is another way of the viral replicaton, it results in the destruction of infected cell and its membrane. In this cycle bacteria make viral DNA and viral protein and break and allow the newly produced virus to leave and now integrated to new cells to spread infection to other cell.
