lysogeenisessä

Lysogeenisessä is a term used in virology to describe a specific type of viral infection where a virus infects a host cell but does not immediately lyse (destroy) the cell. Instead, the viral genome is integrated into the host cell's genome, and the virus remains dormant within the cell. This state is known as lysogenic conversion, and the infected cell is referred to as a lysogen.

The lysogenic cycle can last for an extended period, during which the viral genome is replicated along with the host cell's DNA. The virus can remain dormant for generations, and the infected cell can continue to divide and function normally. However, under certain conditions, such as stress or changes in the host cell's environment, the viral genome can be activated, leading to the production of new viral particles and the eventual lysis of the host cell.

Lysogeenisessä is a common strategy employed by many viruses, including bacteriophages, which infect bacteria. This strategy allows the virus to persist within the host population and potentially spread to new hosts. The lysogenic cycle is an important aspect of viral evolution and has significant implications for both viral and host biology.
