Scientists discover second, secret DNA code

WASHINGTON (AFP) - Scientists have long believed that DNA tells the cells how to make proteins. But the discovery of a new, second DNA code on 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.
