Compete online to design new viable patterns of ribonucleic acid or RNA. You know, those chains of four bases: adenine, cytosine, guanine and uracil that stick together in specific pairings to turn genes on or off. You fold ‘em, you match ‘em to make unique structures. The best designs are chosen every week to be synthesized in an actual laboratory to see how well they would hold up in real life. Don’t worry if you know nothing about genetics. There are tutorials to show you what to do. This online game was developed by scientists at Carnegie Mellon University and Stanford University.
