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:

    “It is commonly said, and more particularly by Lord Shaftesbury, that ridicule is the best test of truth; for that it will not stick where it is not just. I deny it. A truth learned in a certain light, and attacked in certain words, by men of wit and humour, may, and often doth, become ridiculous, at least so far, that the truth is only remembered and repeated for the sake of the ridicule.”
    —Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    “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)
