The universe only gives the impression it's designed because that is how human minds work. We look for patterns in everything; it's the basis for our societies.
DNA is far from designed though. It isn't even very complex at all. Consider the English alphabet; it contains 26 letters (27 if you include spaces) and even more if you list all the punctuation etc. That is very complex! DNA on the other hand, is made up of 4 "letters" A,C,G,T and is simply a sequence of pairs. It is what defines us as human, although one single mutation in that code doesn't make much of a difference at all. You could mutate who sections of code and still end up with a human, because the length of it is so large (Human genome is about 700MB of text). Hardly a good "design" when you think about it, because so many mutations can can have negative results (and they indeed do).
