Well. gene duplication with subsequent divergence is equivalent to new information. In fact, the duplication itself is technically an increase of information. The subsequent divergence is produced through selection by the environment.
Remember that there is no law of 'conservation of information', so technically, information doesn't have to 'come from' anywhere. if that isn't satisfying, think about how *every* causal interaction actually produces information by allowing 'backtracking' to original conditions.
As others have pointed out, simple morphology of the molecules is a type of information that constrains subsequent reactions. In fact, that is one *primary* aspect of information that is most relevant to the biology of enzymes for example. Polarity is another big informational aspect of most molecules (including nucleotides).
