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:

    “Manners are the happy way of doing things; each once a stroke of genius or of love—now repeated and hardened into usage. They form at last a rich varnish, with which the routine of life is washed, and its details adorned. If they are superficial, so are the dewdrops which give such depth to the morning meadows.”
    —Ralph Waldo Emerson (1803–1882)

    “Reminiscences, even extensive ones, do not always amount to an autobiography.... For autobiography has to do with time, with sequence and what makes up the continuous flow of life. Here, I am talking of a space, of moments and discontinuities. For even if months and years appear here, it is in the form they have in the moment of recollection. This strange form—it may be called fleeting or eternal—is in neither case the stuff that life is made of.”
    —Walter Benjamin (1892–1940)
