Researchers at the University of California San Diego have shown that an enzyme called RNA polymerase can accurately transcribe an expanded eight-letter DNA alphabet, which includes synthetic base pairs not found in nature. This was demonstrated through biochemical experiments and cryo-electron microscopy, revealing how the enzyme recognizes and incorporates synthetic bases using the same mechanisms as natural bases. A separate study published in PNAS showed that RNA polymerase can also recognize synthetic base pairs without relying on hydrogen bonds. These findings advance synthetic biology by demonstrating that natural molecular machinery can process synthetic genetic information, potentially enabling new medical applications like targeted cancer diagnostics.
