Proof that you can add information to DNA:

Take an organism, say we call it A. Suppose that its offspring suffers a mutation in its genome. According to creationist dogma, this must either result in no change in the amount of information, or a loss of information. Let's assume for the sake of argument that it results in a loss of information. By definition, this new organism, B, has less information than A. Now suppose that B's offspring suffers a mutation which changes its DNA back to that which it was in A. Call this organism C. Because A has more information than B, and A and C have the same information, organism C's DNA has more information than B's DNA (by transitivity). Thus, by mutation, an increase in information was observed.

QED.

 You are somewhat correct, but I think you have left out part of what Creation science knows. The info in B was never lost in the sense it just left, it is no longer active, it's recessive. So when C is born and looks like A the info became active again, we can see this in dog breeding today. I've breed down unfavorable traits in dogs just to have them pop up again.

You're simply altering the hypothetical in order to avoid the conclusion. Do you deny that information in the genome can be lost due to mutation? In no clear sense does the term recessive apply. Recessive traits can express themselves without a change in the DNA. This is not at all analogous to the hypothetical given. The hypothetical given was an example where the information was actually lost. You're simply choosing not to answer the hypothetical.
