The lysogenic and lytic cycles are two different ways in which viruses can reproduce and infect host cells.
In the lytic cycle, the virus injects its genetic material (DNA or RNA) into the host cell. Once inside, the viral genetic material takes over the host cell's machinery and uses it to replicate its own genetic material. The host cell then produces viral proteins, as directed by the viral genetic material, and assembles new viruses. Eventually, the host cell is lysis, or ruptures, releasing the newly formed viruses that can go on to infect other cells.
In contrast, the lysogenic cycle involves the integration of the viral genetic material into the host cell's DNA. Rather than immediately taking over the host cell's machinery and producing new viruses, the viral genetic material becomes part of the host cell's own genome and is replicated along with it during cell division. The integrated viral genetic material is called a prophage or provirus. In this state, the virus does not cause immediate harm to the host cell, and it can persist for long periods of time within the host genome. However, under certain conditions, such as stress or environmental cues, the prophage may become active and enter the lytic cycle, leading to the production of new viruses and the destruction of the host cell.

The key difference between the lysogenic and lytic cycles is that the host cell is destroyed during the lytic cycle, while it can survive while harboring the viral DNA in the lysogenic cycle.
Why do doctors recommend people get the flu vaccine every year rather than every few years?(1 point) Responses They should get the flu vaccine because their bodies already have a resistance. They should get the flu vaccine because their bodies already have a resistance. They should get the flu vaccine because their bodies do not build up resistance. They should get the flu vaccine because their bodies do not build up resistance. They should get the flu vaccine because viruses mutate. They should get the flu vaccine because viruses mutate. They should get the flu vaccine because viruses do not mutate. They should get the flu vaccine because viruses do not mutate.
Doctors recommend people get the flu vaccine every year rather than every few years because viruses, including the influenza virus, can mutate. Viral mutations can result in new strains of the virus that may not be effectively targeted by previously developed vaccines. By receiving the flu vaccine annually, individuals increase their chances of being protected against the most recent and prevalent strains of the flu virus.
