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 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.
