Long non-coding RNA molecules necessary to regulate differentiation of embryonic stem cells into cardiac cells
When the human genome was sequenced, biologists were surprised to find that very little of the genome—less than 3 percent—corresponds to protein-coding genes. What, they wondered, was all the rest of ...
