  2. Filamentous bacteriophage - Wikipedia

    en.wikipedia.org/wiki/Filamentous_bacteriophage

    Genetic studies on M13 using conditional lethal mutants, initiated by David Pratt and colleagues, led to description of phage gene functions. [ 32 ] [ 33 ] Notably, the protein product of gene 5, which is required for synthesis of progeny single-stranded DNA, is made in large amounts in the infected bacteria, [ 34 ] [ 35 ] [ 36 ] and it binds ...

  3. Bacteriophage - Wikipedia

    en.wikipedia.org/wiki/Bacteriophage

    An example of a bacteriophage known to follow the lysogenic cycle and the lytic cycle is the phage lambda of E. coli. [53] Sometimes prophages may provide benefits to the host bacterium while they are dormant by adding new functions to the bacterial genome, in a phenomenon called lysogenic conversion.

  4. Phage display - Wikipedia

    en.wikipedia.org/wiki/Phage_display

    In this way, large libraries of proteins can be screened and amplified in a process called in vitro selection, which is analogous to natural selection. The most common bacteriophages used in phage display are M13 and fd filamentous phage , [ 2 ] [ 3 ] though T4 , [ 4 ] T7 , and λ phage have also been used.

  5. 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.

    en.wikipedia.org/wiki/Bacterial_cellular...

    A coccus (plural cocci, from the Latin coccinus (scarlet) and derived from the Greek kokkos (berry)), is any microorganism (usually bacteria) [1] whose overall shape is spherical or nearly spherical. [2] [3] [4] Coccus refers to the shape of the bacteria and can contain multiple genera, such as staphylococci or streptococci. Cocci can grow in ...

  7. Lambda phage - Wikipedia

    en.wikipedia.org/wiki/Lambda_phage

    The integration of phage λ takes place at a special attachment site in the bacterial and phage genomes, called att λ. The sequence of the bacterial att site is called attB, between the gal and bio operons, and consists of the parts B-O-B', whereas the complementary sequence in the circular phage genome is called attP and consists of the parts ...

  8. Virion - Wikipedia

    en.wikipedia.org/wiki/Virion

    Multiple shapes of virions. Since the genome of viruses is relatively simple, the capsid architecture relies on repetition of simple structures, similar to the faces of a polyhedron. Each face in turn is formed by a repetition of simpler sub-units, with the amount of repetitions called a triangulation number (T). Similar capsid structures can ...

  9. Bacterial morphological plasticity - Wikipedia

    en.wikipedia.org/wiki/Bacterial_morphological...

    Bacterial morphological plasticity refers to changes in the shape and size that bacterial cells undergo when they encounter stressful environments. Although bacteria have evolved complex molecular strategies to maintain their shape, many are able to alter their shape as a survival strategy in response to protist predators, antibiotics, the immune response, and other threats.
