Lytic Cycle
it does it like any other virus
mononucleosis is not infectious
In a bacterial lysogenic life cycle, the virus integrates its DNA into the host's genome and replicates along with the host cell. In a lytic life cycle, the virus infects the host cell, replicates rapidly, and then bursts the cell to release new viral particles.
Measles goes through the lytic life cycle, where the virus enters a host cell, replicates, and then destroys the host cell to release new viral particles. This leads to symptoms associated with the infection.
It's a good question. Some people argue that viruses AREN'T really alive in the usual sense but occupy a zone between life and nonlife. The tobacco mosaic virus, for instance, can sort of "dry up" into a crystal which shows no signs of life but these crystals, injected into a tobacco plant, can produce more viruses, and reproduction is a sign of living things. It might interest you to know that "virus" is from the Latin word for "slime," so people didn't think of them so much as "things" but more as "stuff."
The typical life cycle of a DNA virus involves attachment to the host cell, entry into the cell, replication of viral DNA and production of new virus particles, and finally release of these new viruses to infect other cells.

The easiest way to understand how viruses replicate is to study the life cycles of viruses called bacteriophages (bacteria eaters). Bacteriophages replicate by either a lytic cycle or a lysogenic cycle. The difference in these two cycles is that the cell dies at the end of the lytic cycle or the cell remains in the lysogenic cycle. The virus remains "hidden".
The phases of a computer virus life cycle typically include: infection, replication, activation, and spread. During the infection phase, the virus gains entry into a system. In the replication phase, the virus creates copies of itself to spread further. Activation occurs when the virus is triggered to execute its malicious payload. Finally, the virus spreads by infecting other systems through various means.
Because it infects bacteria and uses it as a factory to replicate and create more bacteriophage. T2 Bacteriophage undergoes lytic life cycle and NOT lysogenic life cycle
A virus is a microscopic particle that invades a cell, takes over its machinery to replicate, and ultimately destroys the cell as part of its life cycle.
