A virus is RNA and DNA surrounded by protein. A virus can not live alone without a host cell. The life cycles are: attachment, penetration, uncoating, replication and release. During the release process, viruses may escape from the host cell by causing cell rupture viruses typically "bud" from the host cell. During the budding process, a virus acquires the phospholipid envelope containing the embedded viral glycoproteins.
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.
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.
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.
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 lysogenic cycle. This is when the virus incorporates its genetic material into the hosts genetic material and becomes what is called a provirus.
During the cycle of viral shedding, the virus has made copies of itself and the host cell is no longer useful. The host cell then dies, and the new virus cells then must find a new host.
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.
Warts are caused by a virus called human papillomavirus (HPV). The life cycle of a wart typically involves the virus entering the skin through a cut or abrasion. The virus then infects the skin cells, causing them to grow rapidly and form a raised bump known as a wart. Over time, the body's immune system may recognize the virus and attack it, leading to the wart eventually disappearing on its own. In some cases, warts may persist and require treatment to remove them.
