You're using "Isolated DNA" to mean cDNA (a point that I think needs clarifying; you can isolate DNA from cells through other methods). Your metaphor doesn't seem particularly solid to me; it would be more accurate to say that DNA is source code, proteins (and hence enzymes) are object code, and mRNA is code that has been pulled out from disk (the genome), had its comments (introns, as you point out) removed, but is not yet compiled. The computing metaphor obviously breaks down; the best way to characterize cDNA I can think of is as code that's been intercepted on its way to the compiler and placed back into storage - for it to be reverse-engineered object code, it would need to be derived from proteins, which it is not.
