Repeated Sequence (DNA)

Repeated Sequence (DNA)

In the study of DNA sequences, one can distinguish two main types of repeated sequence:

  • Tandem repeats:
    • Satellite DNA
    • Minisatellite
    • Microsatellite
  • Interspersed repeats:
    • SINEs (Short Interspersed Nuclear Elements)
    • LINEs (Long Interspersed Nuclear Elements)

In primates, the majority of LINEs are LINE-1 and the majority of SINEs are Alu's.

In prokaryotes, CRISPR are arrays of alternating repeats and spacers.

Famous quotes containing the words repeated and/or sequence:

    The poem of the mind in the act of finding
    What will suffice. It has not always had
    To find: the scene was set; it repeated what
    Was in the script.
    Then the theatre was changed
    To something else. Its past was a souvenir.
    Wallace Stevens (1879–1955)

    We have defined a story as a narrative of events arranged in their time-sequence. A plot is also a narrative of events, the emphasis falling on causality. “The king died and then the queen died” is a story. “The king died, and then the queen died of grief” is a plot. The time sequence is preserved, but the sense of causality overshadows it.
    —E.M. (Edward Morgan)
