 A palindromic structure allows the Y chromosome to repair itself by bending over at the middle if one side is damaged.Palindromes also appear to be found frequently in the peptide sequences that make up proteins, but their role in protein function is not clearly known.It has been suggested that the existence of palindromes in peptides might be related to the prevalence of low-complexity regions in proteins, as palindromes are frequently associated with low-complexity sequences.
