Question

Which of the following DNA sequences qualifies be designated as a palindrome? (A)  5GACGAG-3 3-CTGGTC-5  (B)  5-AGCGCT-3 3-TCGCGA-5  (C)  3-GACCAG-5 in one strand (D)  5-GACCAG-3 in one strand

Palindrome is a section of double stranded DNA in which the sequence of bases on one DNA strand is inverted and repeated with that on other strand. Thus, the following sequence is palindromic 5-AGCGCT-3 3-TCGCGA-5 Palindromic sequences are common in DNA and are the sites at which the DNA is cleaved by restriction enzymes.
