Second DNA code: New elements of DNA found, 'duons' affect protein/gene control

Word of a second DNA code has reached human ears and might portend tremendous implications for our study of humankind. The most recent reports on this discovery share that a new element of DNA has been found, called duons, which serve to both inform protein sequence development and that of gene control. Fox News offers the information this Friday, Dec. 13, 2013.

The impact of this second DNA code on our study of human life has not been fully realized just yet, but it was found in a location that’s almost as stunning as the human life find itself. Rather than discovering this new code in an unknown location, it was actually discovered right on the veneer of the DNA code that scientific researchers found years ago — weaved in secretly, if you will.

It appears that these multipurpose duons not only work to “teach” the body on how to create all-important proteins, but also on the still murky process of gene control. Mutations that come with age or as a natural reaction to viruses within this second DNA code, for example, could have a much more significant function than researchers realized in the past through this massive find.

"For over 40 years we have assumed that DNA changes affecting the genetic code solely impact how proteins are made," said lead author John Stamatoyannopoulos, University of Washington associate professor of genome sciences and of medicine. “Now we know that this basic assumption about reading the human genome missed half of the picture … Many DNA changes that appear to alter protein sequences may actually cause disease by disrupting gene control programs or even both mechanisms simultaneously."

While a 64-letter alphabet of codons was already known as the basic elements of DNA within the genetic code, this second DNA code finds that with this hidden strand, duons serve as key players in the construction of our deoxyribonucleic language, affecting both protein sequence and the body’s controlling of genes.

The latter instructions "appear to stabilise certain beneficial features of proteins and how they are made," the study said.

More research on this amazing discovery surrounding the second DNA code is being investigated by the U.S. National Human Genome Research Institute.
