You need to know what pattern is at the biological level before you can discover that DNA is its genetic code.  Therefore, DNA cannot be the criteria for the biological level, only a derivative symptom of it.

I don't, of course, nor do I know what scrambled eggs taste like to anyone else but me.  But this doesn't prevent me from knowing all sorts of things about other living things' experience.  For instance, I know an amoeba doesn't value acid, because I see it back away.
