Web10 apr. 2024 · Phage generally has two different cycles: the lytic and lysogenic cycles. Both processes start accompanying the phage’s affection for the bacterial host’s surface after a dose of the phage’s hereditary material into the container. In the lytic phase of phages, the bacteriophage genome produces proteins that degrade the bacterial genome. Web22 mai 2024 · In addition to the lytic pathway, certain bacteriophage (i.e. ‘temperate’ bacteriophage) can also initiate lysogeny, a latent mode of infection in which the viral genome is integrated into and replicated with the bacterial chromosome.
