  2. 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.

  3. Bacteriophage - Wikipedia

    en.wikipedia.org/wiki/Bacteriophage

    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. T4 rII system - Wikipedia

    en.wikipedia.org/wiki/T4_rII_system

    The T4 rII system is an experimental system developed in the 1950s by Seymour Benzer for studying the substructure of the gene. The experimental system is based on genetic crosses of different mutant strains of bacteriophage T4 , a virus that infects the bacteria Escherichia coli .

  5. Phage typing - Wikipedia

    en.wikipedia.org/wiki/Phage_typing

    The binding process is known as adsorption. [5] Once a phage adsorbs to the surface of a bacteria, it may undergo either the lytic cycle or the lysogenic cycle. [6] Virulent phages enter the lytic cycle where they replicate and lyse the bacterial cell. [7]

  6. Lysogenic cycle - Wikipedia

    en.wikipedia.org/wiki/Lysogenic_cycle

    Lysogenic cycle, compared to lytic cycle Lysogenic Cycle:1. The prokaryotic cell is shown with its DNA, in green. 2. The bacteriophage attaches and releases its DNA, shown in red, into the prokaryotic cell. 3. The phage DNA then moves through the cell to the host's DNA. 4. The phage DNA integrates itself into the host cell's DNA, creating ...

  8. Temperateness (virology) - Wikipedia

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

    Temperate phages can switch between a lytic and lysogenic life cycle. Lytic is more drastic, killing the host whereas lysogenic impacts host cells genetically or physiologically. [4] [5] [6] Here is a chart on temperate phages that are lytic and lysogenic and how they're related. Lysogeny is characterized by the integration of the phage genome ...
