Find the palindrome in this restriction enzyme site: 5'-CTGCAG-3'?

A patient with impaired judgment, personality changes, signs of abnormal
body movements and depression comes to the physician's office for a
follow-up visit. The physician suspects a single-gene disorder may be the
cause of those clinical manifestations. A blood specimen was then sent to
your clinical laboratory for mutation screening in the Huntington gene.
Testing with standard PCR indicates that patient has Huntington Disease, HD.
Which of the following would be consistent with this diagnosis?
25 CAG repeats in the Huntington gene
85 CAG repeats in the Huntington gene
25 CGA repeats in the Huntington gene
85 CGA repeats in the Huntington gene - correct answers 85 CAG repeats in
the Huntington gene

16 and 18
31 and 59
16 and 58
