Second DNA code: Uncovering part 2 of DNA, what it means

A second DNA code discovered by scientists now makes a complete picture of DNA readings. A team of scientists at the University of Washington have learned of a second code hidden with DNA that ties together with the first half.

Time Science and Space reports Dec. 13 that since the first DNA code was deciphered in the early 1960s, it was unknown a second DNA code was missing.

“Now we know that this basic assumption about reading the human genome missed half of the picture,” said team leader Dr. John Stamatoyannopoulos.

The first code backed up how proteins are made and the second code instructs the cell on how many genes are to be controlled, the report revealed. This latest discovery by scientists will be published in Science magazine Friday. This is good news, as it will allow for more accurate diagnoses and treatments put in motion for disease.

Scientists say the first code was "written on top of the other" code, thus taking more meticulous study to discover the second DNA code.

Finding the second DNA code was part of a project titled "Encyclopedia of DNA Elements Project" -- also known as ENCODE. It was funded by The National Human Genome Research Institute as part of a multi-year, international study.
