Scientists discover second, secret DNA code
Scientists have long believed that DNA tells the cells how to make proteins. But the discovery of a new, second DNA code Thursday suggests the body speaks two different languages.
The findings in the journal Science may have big implications for how medical experts use the genomes of patients to interpret and diagnose diseases, researchers said.
The newfound genetic code within deoxyribonucleic acid, the hereditary material that exists in nearly every cell of the body, was written right on top of the DNA code scientists had already cracked.
Rather than concerning itself with proteins, this one instructs the cells on how genes are controlled.
Its discovery means DNA changes, or mutations that come with age or in response to viruses, may be doing more than what scientists previously thought, he said.
"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," he said.
"Many DNA changes that appear to alter protein sequences may actually cause disease by disrupting gene control programs or even both mechanisms simultaneously."
Scientists already knew that the genetic code uses a 64-letter alphabet called codons.
But now researchers have figured out that some of these codons have two meanings.
Coined duons, these new elements of DNA language have one meaning related to protein sequence and another that is related to gene control.
The latter instructions "appear to stabilize certain beneficial features of proteins and how they are made," the study said.
The discovery was made as part of the international collaboration of research groups known as the Encyclopedia of DNA Elements Project, or ENCODE.
It is funded by the US National Human Genome Research Institute with the goal of finding out where and how the directions for biological functions are stored in the human genome.

Police face questions over the influence of the Freemasons
South Yorkshire Police today face questions over whether powerful 'secret society' the Freemasons held sway over the force at the time of Hillsborough.
Families of victims say that officers who were Masons were promoted into powerful positions despite being ill-equipped, including match commander David Duckenfield.
Duckenfield told the fresh inquests he had been a Freemason since 1975 and became head of his ...

Half of Western European men descended from one Bronze Age ‘king’
Half of Western European men are descended from one Bronze Age ‘king’ who sired a dynasty of elite nobles which spread throughout Europe, a new study has shown.
The monarch, who lived around 4,000 years ago, is likely to have been one of the earliest chieftains to take power in the continent.
He was part of a new order which emerged in ...
"Local Residents" Are Filmed Stealing Dozens of Bottles of Water at London Marathon Stop
Editor's Comment: "Local" residents? Why bother blurring their faces? We know who they are.
London marathon runners were robbed of dozens of bottled waters when thieves raided a refreshment area armed with trolleys during today's race.
Nearby residents - including parents with children - were captured on camera piling up crates of free water handed out by volunteers during the 26-mile event.
