  2. Temperateness (virology) - Wikipedia

    en.wikipedia.org/wiki/Temperateness_(virology)

    In virology, temperate refers to the ability of some bacteriophages (notably coliphage λ) to display a lysogenic life cycle. Many (but not all) temperate phages can integrate their genomes into their host bacterium's chromosome, together becoming a lysogen as the phage genome becomes a prophage .

    Structural model at atomic resolution of bacteriophage T4 [1] The structure of a typical myovirus bacteriophage Anatomy and infection cycle of bacteriophage T4.. A bacteriophage (/ b æ k ˈ t ɪər i oʊ f eɪ dʒ /), also known informally as a phage (/ ˈ f eɪ dʒ /), is a virus that infects and replicates within bacteria and archaea.

  4. Enterobacteria phage P4 - Wikipedia

    en.wikipedia.org/wiki/Enterobacteria_phage_P4

    Enterobacteria phage P4 (also known as satellite phage P4) is a temperate bacteriophage strain of species Escherichia virus P2 within genus Peduovirus (formerly P2-like viruses, P2virus, and P2likevirus), subfamily Peduovirinae, family Myoviridae. [1] It is a satellite virus, requiring P2-related helper phage to grow lytically.

  5. Escherichia virus T4 - Wikipedia

    en.wikipedia.org/wiki/Escherichia_virus_T4

    In order for the T-even phage to infect its host and begin its life cycle it must enter the first process of infection, adsorption of the phage to the bacterial cell. Adsorption is a value characteristic of phage-host pair and the adsorption of the phage on host cell surface is illustrated as a 2-stage process: reversible and irreversible.

  6. Lambda phage - Wikipedia

    en.wikipedia.org/wiki/Lambda_phage

    Lambda phage is a non-contractile tailed phage, meaning during an infection event it cannot 'force' its DNA through a bacterial cell membrane. It must instead use an existing pathway to invade the host cell, having evolved the tip of its tail to interact with a specific pore to allow entry of its DNA to the hosts.

  7. Prophage - Wikipedia

    en.wikipedia.org/wiki/Prophage

    A prophage is a bacteriophage (often shortened to "phage") genome that is integrated into the circular bacterial chromosome or exists as an extrachromosomal plasmid within the bacterial cell. [1] Integration of prophages into the bacterial host is the characteristic step of the lysogenic cycle of temperate phages.

  8. Bacteriophage P2 - Wikipedia

    en.wikipedia.org/wiki/Bacteriophage_P2

    Bacteriophage P2 is a temperate phage, which means that it can propagate lytically (i.e. directing the host cell to produce phage progenies and finally lysing the host when the phage progenies exit), as well as establish lysogeny (i.e. injecting and fusing its genetic material into the genome of the host without lysing the cell) and maintain as ...

  9. Salmonella virus P22 - Wikipedia

    Schematic drawing of an Entero­bacteria phage P22 virion (cross section and side view) P22 shares many similarities in genetic structure and regulation with bacteriophage λ . [ 1 ] It is a temperate double stranded DNA phage as well as a lambdoid phage since it carries control of gene expression regions and early operons similar to those of ...
