在字符{A, C, G, T}组成的DNA序列中,A和T、C和G是互补对。判断一个DNA序列中是否存在互补回文串(例如,ATCATGAT的补串是TAGTACTA,与原串形成互补回文串)。下面DNA序列中存在互补回文串的是:(多选) In the DNA sequences consisting of character {A, C, G, T}, A and T, C and G are complementary pairs. Judging whether there is a complementary palindrome sequence in a DNA sequence (e.g., ATCATGAT’s complement strings is TAGTACTA, it is complementary palindrome sequence with the original sequence). Which of the following DNA sequences have complementary palindrome string? (There are more than one answers.)
A、CTGATCAG
B、AATTAATT
C、TGCAACGT
D、CATGGTAC
E、GTACGTAC
F、AGCTAGCT

在字符{A, C, G, T}组成的DNA序列中,A —— T和C —— G是互补对。 判断一个DNA序列中是否存在互补回文串(例如,ATCATGAT的补串是TAGTACTA,与原串形成互补回文串;即要求整个原串的补串是原串的逆序); 下面DNA序列中存在互补回文串的是:(多选) In DNA sequences consisting of characters {A, C, G, T}, A - T and C - G are complementary pairs respectively. Determine whether a DNA sequence has a complementary palindromic string (For example, ATCATGAT's complementary string is TAGTACTA, with is the palindromic sequence to the original string; in such case the complementary string is also the reverse of the original string); Which of the following DNA sequences have complementary palindromic string? (multiple choice)
A、CTGATCAG
B、AATTAATT
C、GTACGTAC
D、AGCTAGCT
