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.

Other types of repeats

Note: The following are covered in detail in "Computing for Comparative Microbial Genomics".^[1]

• Direct repeats
  • Global direct repeat
  • Local direct simple repeats
  • Local direct repeats
  • Local direct repeats with spacer
• Inverted repeats
  • Global inverted repeat
  • Local inverted repeat
  • Inverted repeat with spacer
  • Palindromic repeat
• Mirror and everted repeats
