"DNA is simply a naturally occurring acid, and as such has not increased in complexity." [excerpt]
Its not simply a 'naturally occurring acid'.
DNA is a naturally occurring acid and genes can be assembled in complex patterns by using DNA. You are confusing what is done with the chemical and the chemical itself.
I suggest you do further research on this subject before asserting this type of thing without sources to back up your claims.
I am very familiar with DNA, RNA, transpose genes, etc. Did you know that apx. 60% of the material in your genes come from viruses? The more interesting question that you should be asking is, what controls the RNA to transcribe selected portions of the gene sequences. That is where the cutting edge research is.
