The correct answer option is (D) palindromic sequence.
Why the correct option is correct
- (D) palindromic sequence: A palindromic sequence consists of inverted repeats that read the same way in forward and backward directions on complementary strands. When a single strand of nucleic acid contains a palindromic sequence, it possesses regions that are perfectly complementary to each other. This allows the single strand to fold back on itself and engage in intrastrand base-pairing, naturally giving rise to a highly stable hairpin (or stem-loop) structure.
