It seems that DNA is far more complicated and intricately configured than we originally thought - see Scientists Say They’ve Found a Code Beyond Genetics in DNA - New York Times. So much so that the author of this article slips into "design talk" towards the end:

Biologists have long speculated that the redundancy may have been designed so as to coexist with some other kind of code, and this, Dr. Segal said, could be the nucleosome code.

It is hard not to see design with interconnected coding which produces a certain designed functionality. In any other world we would say "Someone made this to work like that!" - Yet we still know better.
