This flexible molecule tells the cell’s protein-making factories what DNA wants them to do, stores genetic information and may have helped life get its start. More than just DNA’s lesser-known cousin, RNA plays a central role in turning genetic information into your body’s proteins.

Is RNA same as DNA?

DNA and RNA are very similar. After all, RNA is supposed to be a copy of DNA. … RNA, on the other hand, is a single-stranded molecule.
