It is a palindrome that reads the same on both strands.

Explanation: GAATTC is a palindromic 6‑bp sequence (5' GAATTC 3' on one strand complements 5' GAATTC 3' on the other). Many restriction enzymes are homodimers that recognize symmetric (palindromic) sites and cleave both DNA strands at or near that symmetry.
