What is Lysogenic Cycle? Definition of Lysogenic Cycle Advertisements The lysogenic cycle is a viral replication process in which a virus integrates its genetic material into the host cell’s genome, allowing it to remain dormant and propagate without immediately destroying the host. This dormant viral DNA, known as a prophage, can later be activated to … Read more
What is Lytic Cycle? Advertisements The lytic cycle is a fundamental process in the life cycle of certain viruses, particularly bacteriophages, which are viruses that infect bacteria. This cycle is characterized by the following sequential events: The term “lytic” is derived from “lysis,” referring to the rupture and death of the host cell. This cycle … Read more
What is Lytic Cycle? Definition of Lytic Cycle Advertisements The lytic cycle is a phase of viral reproduction wherein a virus infects a host cell, utilizes the cell’s machinery to replicate, and subsequently causes the cell to burst (lyse), releasing new virions to infect other cells. Bacteriophage(virus) Life cycle of bacteriophage Steps of the Lytic … Read more
What is Microevolution? Definition of Microevolution Advertisements Microevolution refers to small-scale changes in allele frequencies within a population over a relatively short period of time, driven by mechanisms such as mutation, selection, gene flow, and genetic drift.
