If you had a four-letter alphabet and all words were three letters, then how many words would there be? The answer is 4 times 4 times 4, or 4-cubed, or 4^3, or 64. That’s how the DNA code works. Our DNA has four molecular “letters” and to create a protein the letters are taken three at a time in words called “codons.” Each codon specifies an amino acid and these 64 different codons are mapped to 20 different amino acids (and a “stop” signal). Since the 64 different codons far exceeds the 20 different amino acids and the stop signal, the code is degenerate. In other words, there are multiple codons that map the same amino acid (just as “absurd” and “ludicrous” have similar meanings).
But why the mismatch? If only 20 different amino acids are coded for, why are there 64 different codons? There is quite a bit of unused messaging power, or what engineers call “bandwidth.” According to evolutionists, it was just another biological kludge revealing nature’s dysteleology.
But ever since its discovery the DNA code has continued to yield hidden treasures of intricacy. For example, the code is cleverly designed at several levels, including minimizing the effects of errors and maximizing information content (such as in supporting overlapping messages).
This makes it even more difficult for evolutionists to explain how the code evolved.
Furthermore the code’s unused bandwidth has been found to be used in a variety of creative ways where additional information is layered on the basic message indicating the amino acid sequence. You can see some examples here, here, here and here.
The new UCSF paper is another such an example of yet another layer of information in the “unused” bandwidth that evolutionists thought was just an inefficient fluke. It has been known for years that a DNA gene, that is used to construct a protein, has some special signals near the beginning that will help the translating process get started correctly.
Now, the new research indicates that similar signals are used throughout the gene. Their purpose is not to help the protein production process get started correctly, but rather to fine-tune the speed of the production process.
It is yet another example of the many different types of information that are layered in a DNA gene which have evolutionists rewriting their script and explaining that “It’s over. None of that happened.”
