A palindromic sequence
is a DNA or RNA sequence that reads the same on the complementary strand
. It is not
a sequence that reads the same forwards and backwards.
- AATCGCGATT is a palindromic sequence,
- AATCGGCTAA is not
Palindromic sequences are interesting because they are hotspot
s for mutation. Palindromic DNA sequences in Bacteria
appear to be more prone to mutation than non-palindromic sequences.
