Palindromic sequence
Palindromic sequence: a DNA or RNA motif identical to its reverse complement, read 5'-to-3' on both strands; basis of restriction enzyme sites (EcoRI GAATTC), hairpin/cruciform structures, genome instability, and the CRISPR name.
Repeated sequence (DNA)
Repeated sequence (DNA), or repetitive DNA, includes tandem repeats (microsatellites, minisatellites, satellite DNA) and dispersed transposable repeats. Over 50% of the human genome is repetitive; repeats mutate rapidly, serve as forensic markers, and cause diseases like Huntington's.
