Lysigeny is a biological term that refers to the transfer of genetic material from a bacteriophage to a host cell without causing immediate lysis of the cell. Some synonyms for lysigeny include lysogenic cycle, temperate phage, and lysogeny. In the lysogenic cycle, the viral genome integrates into the host chromosome and replicates with it, allowing the virus to remain dormant until certain triggers cause it to initiate the lytic cycle and kill the host cell. Understanding lysigeny is critical in the study of bacteriophages and their interactions with bacterial hosts. By identifying these synonyms, researchers can communicate more effectively when discussing the various states and phases of viral infection.
