Detailed explanation-1: -A strand is said to have a palindromic sequence if the sequence of nucleotides is the same as the reverse of its complement. E.g. ACCTAGGT is a palindrome. The complementary strand will have TGGATCCA and if it is reversed then it will be the same as the original sequence.
Detailed explanation-2: -Moreover, CTAG is remark-ably underrepresented relative to its reverse palindromic sequence GATC. To determine the origin of compositional biases, we analyze structural features of palindromic DNA duplexes derived in all-atom molecular simula-tions.
Detailed explanation-3: -In molecular biology it is used as a restriction enzyme. EcoRI creates 4 nucleotide sticky ends with 5’ end overhangs of AATT. The nucleic acid recognition sequence where the enzyme cuts is G↓AATTC, which has a palindromic, complementary sequence of CTTAA↓G.
