Palindromes are a set of words that read the same in both directions. E.g. “madam”.
Palindromic sequences are nucleotide sequences in the DNA duplex or RNA where one strand’s sequence is the same as the corresponding sequence of the other strand when read from the same direction on both strands, either 5′ to 3′ or 3′ to 5′ in molecular biology.
Final Answer : When complementary strands of DNA read the same in both orientations, either from the 5-prime end or the 3-prime end, a palindromic sequence of nucleotides (designated A, T, C, or G) occurs.
