Enterobacteria Phage T4 - Features

Features

The T4 phage has some unique features, such as:

  • Eukaryote-like introns
  • High speed DNA copying mechanism, with only 1 error in 300 copies
  • Special DNA repair mechanisms
  • It infects E. coli O157:H7
  • genome terminally redundant
  • genome first replicated as a unit, and then several genomic units are recombined end-to-end to form a concatemer. When packaged, the concatemer is cut at unspecific positions but of same length, leading to several genomes that represent Circular permutations of the original.

Famous quotes containing the word features:

    These, then, will be some of the features of democracy ... it will be, in all likelihood, an agreeable, lawless, particolored commonwealth, dealing with all alike on a footing of equality, whether they be really equal or not.
    Plato (c. 427–347 B.C.)

    “It looks as if
    Some pallid thing had squashed its features flat
    And its eyes shut with overeagerness
    To see what people found so interesting
    In one another, and had gone to sleep
    Of its own stupid lack of understanding,
    Or broken its white neck of mushroom stuff
    Short off, and died against the windowpane.”
    Robert Frost (1874–1963)

    However much we may differ in the choice of the measures which should guide the administration of the government, there can be but little doubt in the minds of those who are really friendly to the republican features of our system that one of its most important securities consists in the separation of the legislative and executive powers at the same time that each is acknowledged to be supreme, in the will of the people constitutionally expressed.
    Andrew Jackson (1767–1845)
