Repeated sequence (DNA)
- Repeated sequence (DNA)
-
In the study of DNA sequences, one can distinguish two main types of repeated sequence:
- Tandem repeats:
- 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.
