Research dossier · v1 · updated 2026-10-30 · 3,394 words · 58 sources · 29 claims · verification: verified

Where synthetic biology stands in October 2026: genetic circuits, cell-free systems, genome writing and biomanufacturing, with the 2025-2026 steps toward whole-chromosome and AI-designed genomes. The main takeaway is that design tools now outpace the ability to predict how engineered genomes and circuits behave inside living cells.
