  2. 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.

  3. Phage group - Wikipedia

    en.wikipedia.org/wiki/Phage_group

    The isolation of conditional lethal mutants of phage during 1962-1964 by the phage group members provided an opportunity to study the function of virtually all of the genes that are essential for growth of the phage under laboratory conditions. [28] [29] One class of conditional lethal mutants is known as amber mutants. [30]

  4. Escherichia virus T4 - Wikipedia

    en.wikipedia.org/wiki/Escherichia_virus_T4

    During 1962-1964 phage T4 researchers provided an opportunity to study the function of virtually all of the genes that are essential for growth of the phage under laboratory conditions. [43] [44] These studies were facilitated by the discovery of two classes of conditional lethal mutants. One class of such mutants is known as amber mutants. [45]

    en.wikipedia.org/wiki/Ff_phages

    Assembled major coat protein, exploded view. The virion is a flexible filament (worm-like chain) about 6 nm in diameter and 900 nm long.Several thousand copies of a small (50 amino-acid residues) elongated alpha-helical major coat protein subunit (the product of gene 8, or p8) in an overlapping shingle-like array form a hollow cylinder enclosing the circular single-stranded DNA genome.

  6. Caudoviricetes - Wikipedia

    en.wikipedia.org/wiki/Caudoviricetes

    However, some tailed bacteriophage genomes can vary quite significantly in nucleotide sequence, even among the same genus. Due to their characteristic structure and possession of potentially homologous genes, it is believed these bacteriophages possess a common origin.

  7. Mycobacteriophage - Wikipedia

    en.wikipedia.org/wiki/Mycobacteriophage

    Mycobacteriophage Bxb1 Structure [1]. A mycobacteriophage is a member of a group of bacteriophages known to have mycobacteria as host bacterial species. While originally isolated from the bacterial species Mycobacterium smegmatis and Mycobacterium tuberculosis, [2] the causative agent of tuberculosis, more than 4,200 mycobacteriophage species have since been isolated from various environmental ...

  8. P1 phage - Wikipedia

    en.wikipedia.org/wiki/P1_phage

    P1 is a temperate bacteriophage that infects Escherichia coli and some other bacteria. When undergoing a lysogenic cycle the phage genome exists as a plasmid in the bacterium [1] unlike other phages (e.g. the lambda phage) that integrate into the host DNA. P1 has an icosahedral head containing the DNA attached to a contractile tail with six ...

  9. 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.
