11. Now, a quick lesson on the
irreducible complexity of DNA, and you will understand that any alteration, mutation, would destroy its usefulness.
DNA is what causes the production of every compound and structure in a cell, and this is why it need be soooooo huge! Even the simplest known living organism has 482 protein-coding genes. This is a total of 580,000 ‘letters,’
7—humans have three billion in every nucleus. (See ‘
The programs of life’, for an explanation of the DNA ‘letters.’)

Quick example of what changing a single one of those 580,000 ‘letters,’ nucleotides, will do the genetic message:
The nucleotides are 'read' in groups of three...Let's say that this short sentence is the information needed for the cell to build a protein, and we’ll use a sentence with three letter words as though the letters were that nucleotide triplet:
"The sun was hot but the old man did not get his hat."
Simple, easily understood.....
This sentence represents a gene....I know, much too short...but it's just an example!
Let's assume that each letter corresponds to a nucleotide base, and each word represents a codon, a triplet. The definition of 'codon:' a unit that consists of three adjacent bases on a DNA molecule and that determines the position of a specific amino acid in a protein molecule during protein synthesis.

So.... via a Darwinian random change, what we would call a mutation, would leave out, or add, any one letter in the message,
watch how it changes the ‘meaning’ of that sentence:
Drop the first letter, and watch what this sentence, "The sun was hot but the old man did not get his hat."…..It becomes
: "hes unw ash otb utt heo ldm and idn otg eth ish at."
Then it is not the same message at all...the 'mutation' makes the DNA meaningless at best....or lethal at worst!
And that is why nearly every single mutation is harmful at best, deadly at worst.
Now apply the idea to the huge DNA molecule....and one can see that Darwin's premise, alterations in the DNA would not produce a new species.....it would destroy the organism.
