An inverted repeat sequence with no intervening nucleotides between the initial sequence and its downstream reverse complement is a palindrome. <br />    EXAMPLE:<br />
        Step 1: start with an inverted repeat: <br />
        Step 2: remove intervening nucleotides: <br />
        This resulting sequence is palindromic because it is the reverse complement of itself.
:::   test sequence (from Step 2 with intervening nucleotides removed)
:::   complement of test sequence
:::   reverse complement     This is the same as the test sequence above, and thus, it is a palindrome.
