The lytic and lysogenic cycles are the two main phases of a virus’ infective lifecycle and route to replication. The lytic cycle, or virulent infection, involves a virus taking control of a host cell ...

Entry into the lytic or the lysogenic cycle is controlled by the lysis-lysogeny transcriptional switch. This switch activates the prophage, resulting in viral replication, host cell lysis, and the ...

Within a lysogenic cycle, the nucleic acid of the bacteriophage is integrated into the host’s genome, ... Virulent Bacteriophages and the Lytic Cycle. News-Medical, viewed 14 June 2025, ...

Bacteriophage (phage): Virus that infects a bacterial host. Lytic cycle/infection: Virus reproduction that destroys its host cell to release virion progeny. Lysogenic cycle/infection: Non ...

Lytic phages including T4 and T7 express proteins such as lysins that cause hydrolysis of a host cell’s peptidoglycan layer, leading to bacterial cell death. 4 In contrast to lytic phages, lysogenic ...

Viruses in different life cycles can promote elemental cycling (e.g., carbon, nitrogen, and phosphorus) by viral lysing or auxiliary metabolic genes (AMGs) metabolisms. Viruses can increase ...

They subsequently have 2 methods of reproducing within these host cells -- the lytic cycle and the lysogenic cycle. Lytic cycle. Used by lytic (or "virulent") type of phage, ...

This terminase complex packages DNA into phage heads during assembly of mature phages, which are released by host lysis. In the alternative lysogenic cycle, phage DNA instead integrates into the host ...

Arbitrium is then released by bacterial cells when they die - sort of like a “this phage was here” marker. Arbitrium is sucked up into neighboring bacterial cells by the OPP transporter. A little bit ...
