Clinical Scorecard: Synthetic DNA Expands the Genetic Alphabet

At a Glance

Key Highlights

• E. coli RNA polymerase can transcribe an expanded genetic alphabet with eight nucleotide letters.
• The study identified a modified base, Z*, that reduces pairing errors with guanine.
• Synthetic pairs P:Z and B:S were shown to be incorporated efficiently by the enzyme.
• Cryo-electron microscopy provided structural insights into enzyme interactions with synthetic bases.
• Further research is needed to establish the reliability of the expanded alphabet in living cells.
