The RAC operates mostly within the Quad, but has been known to extend to acting throughout the J when an operation calls for it. The J-Star Cluster is its own galaxy, and while it does have other planets that are inhabited by humans, their origin is unknown.
Old "Earth" as we know it does not exist in any literature or research within the Quad - if it was relevant to them, it has since faded into near obsolete obscurity.
As for the DNA thing - since this is an actual in-verse law, it would absolutely be outlined specifically. I'm unfamiliar with biology terminology, but however a scientist would say: 30% or more of your body's functions, regardless of necessity to sustained life, being modified falls into illegal territory. DNA and protein expression would both be included in this category, if my understanding is correct - the definition is likely wider reaching than just one type or application of modification.
