[Ben 10] How does the Omnitrix work for seemingly non-organic species?

Such as petrosapiens.

So the Omnitrix is explained to Ben (and the audience) as working by copying the target’s DNA and rewriting Ben’s. This almost certainly a simplification. DNA was just how the genetic code of organic species developed on Earth. Other species throughout the universe all certainly have genetic information that tells their bodies how to form, whether that is coded as a double-helix with the same  nucleotides seems unlikely. 

The omnitrix copies the genetic information of a species whether that resembles DNA or is an entirely different form of code (as in Upgrade’s case it would almost certainly be literal computer code).
