  2. Escherichia virus T4 - Wikipedia

    en.wikipedia.org/wiki/Escherichia_virus_T4

    T4 is capable of undergoing only a lytic life cycle and not the lysogenic life cycle. The species was formerly named T-even bacteriophage, a name which also encompasses, among other strains (or isolates), Enterobacteria phage T2, Enterobacteria phage T4 and Enterobacteria phage T6.

  3. 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 .

  4. 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.

  5. Phage group - Wikipedia

    en.wikipedia.org/wiki/Phage_group

    These experiments, carried out with mutants of the rIIB gene of phage T4, showed, that for a gene that encodes a protein, three sequential bases of the gene's DNA specify each successive amino acid of the protein. Thus the genetic code is a triplet code, where each triplet (called a codon) specifies a particular amino acid.

  6. Phage display - Wikipedia

    en.wikipedia.org/wiki/Phage_display

    Phage display cycle. 1) fusion proteins for a viral coat protein + the gene to be evolved (typically an antibody fragment) are expressed in bacteriophage. 2) the library of phage are washed over an immobilised target. 3) the remaining high-affinity binders are used to infect bacteria. 4) the genes encoding the high-affinity binders are isolated.

  7. Type II topoisomerase - Wikipedia

    en.wikipedia.org/wiki/Type_II_topoisomerase

    The bacteriophage (phage) T4 gyrase (type II topoismerase) is a multisubunit protein consisting of the products of genes 39, 52 and probably 60. [25] [26] It catalyses the relaxation of negatively or positively superhelical DNA and is employed in phage DNA replication during infection of the E. coli bacterial host. [27]

  9. Lysogenic cycle - Wikipedia

    en.wikipedia.org/wiki/Lysogenic_cycle

    The genetic material of the bacteriophage, called a prophage, can be transmitted to daughter cells at each subsequent cell division, and later events (such as UV radiation or the presence of certain chemicals) can release it, causing proliferation of new phages via the lytic cycle.
