Repeated sequence (DNA)

From Wikipedia, the free encyclopedia

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 Elements),
  • LINEs (Long INterspersed Elements).

The majority of LINEs are LINE-1 and the majority of SINEs are ALUs.

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