palindromic sequence
Nucleic acid sequence that is identical to its complementary strand when each is read in the correct direction (eg. TGGCCA). Palindromic sequences are often the recognition sites for restriction enzymes. Degenerate palindromes with internal mismatching can lead to loops or hairpins being formed (as in tRNA).
