medial cuneiform
It lies on the inner side of the foot. It lies in the front of navicular bone and behind the metatarsal.
The message would change because each base has a specific pair that it bonds with. So the original strand's matching sequence would be (ACT GCT) if they were to change the last letter of the first set of 3 numbers, it would be (ACA GCT), and you can see there is a difference in the first sequence of bases. Hope this helps (:
