I understand how natural selection works and consider myself to have a relatively high level of understanding of evolution in general, but if you take things down to the level of DNA as a chemical, what is it getting out of it? Does it even benefit at all (like a lower energetic state etc.) or is the chemistry detached from the biology at this point?

I understand that mutations are random, and that there is no inherent direction in evolution, but what I'm asking is better better described thus; if one takes the view that the gene is the unit of selection in evolution, then what is the gene getting out of it? Just continued survival? And if that is the only thing, why would chemicals 'care' if they continue to exist? Hope this clarifies things a bit.

I have read the Selfish Gene, yes. The wikipedia article about it states, "Describing genes with the term "selfish" is not meant to imply that they have actual motives or will – only that their effects can be accurately described as if they do. The contention is that the genes that get passed on are the ones whose consequences serve their own implicit interests, not necessarily those of the organism, much less any larger level". I understand this, and what I'm asking is, "what are their 'implicit interests'?" - what do they have to gain?
