This has been explained in the part of post #650, that you deleted. So for highlighting:
T-h III in post n° 607:
"For a typical protein length of about 300 amino acids, more than 10^390 different polypeptide chains could theoretically be made. This is such an enormous number that to produce just one molecule of each kind would require many more atoms than exist in the universe."
Driewerf in post n° 617 * gives three examples where under experimental investigation DNA can rearrange and write itself.* writes the phrase "Before the actual gene there is a genetic "switch" in the DNA before the DNA part that codes for a protein. This switch can be activated by a hormone, a the metabolic starting material or any other signal molecule." Note that the word "before" means on the (linear) DNA sequence, not a temporal sequence.
T-h III in post #645: " "Before the actual gene there is a genetic "switch" in the DNA before the DNA part that codes for a protein."
Where did the DNA come from? How about the machinery to interpret DNA? did they evolve at the same time? If so, what luck!!!!"
And here the goalposts have moved. From "DNA can't write itself" - despite three well documented examples provided we have move to "Where did the DNA came from.?" and the request to explain how the machinery to read the DNA evolved. That are the goalposts that have been moved. But T-h III prefers to play the ignorance card.
Instead of showing integrity and admitting the his "rebuttal from math" has been shown to be bonkers, a new challenge is issued.
