lysogeeniseen

Lysogeeninen refers to a specific type of viral replication cycle known as the lysogenic cycle. This cycle is a characteristic of bacteriophages, viruses that infect bacteria. In the lysogenic cycle, the viral DNA, or prophage, integrates into the host bacterium's chromosome. It does not immediately take over the host's machinery to produce new virus particles. Instead, the prophage remains dormant, replicating along with the bacterial DNA during cell division. The host cell, now containing the prophage, is called a lysogenic bacterium.

This state can persist for many generations. However, under certain environmental conditions, such as stress on the host cell, the prophage can be induced to enter the lytic cycle. The lytic cycle involves the activation of viral genes, leading to the synthesis of new phage particles, and ultimately, the lysis or bursting of the host cell, releasing these new viruses. The lysogenic cycle is advantageous to the virus as it allows for the propagation of viral DNA within a bacterial population without necessarily killing the host immediately, thus ensuring a longer-term survival strategy. This process is distinct from the lytic cycle, where viral replication leads to rapid destruction of the host cell.
