You seem to be focusing on the pressence of protein while I am highlighting the arrangement of it. It's in the arrangement that I believe shows evidence for Intellegent Design.
If a bunch of random RNA or DNA sequences are produced, some of them
will have (or produce proteins with) specific activity. In fact, laboratories trying to find RNA sequence with specific activity use a random method. If they try to design the sequence, they fail; however, producing a million or so random RNA sequences, then selecting ones with activity, has allowed identification of many RNA sequences with highly specific activity.
Thus, no intelligence is needed for "the arrangement" of DNA, since random DNA sequence produces meaningful, specific biological activity.
Quite the opposite of evidence for intelligent design.
