1 · What it gives

DNA synthesis and the gene foundry are the “write-and-build” service layer of synthetic biology: a researcher designs a sequence on a computer and a service provider chemically synthesises the gene, clones it and ships it back, or builds the whole strain through a Design-Build-Test-Learn (DBTL) foundry loop. The established chemistry is phosphoramidite synthesis, which adds bases one at a time to a growing chain but is capped at roughly 200 to 300 nucleotides per oligo; genes are then assembled enzymatically into fragments up to about 3000 base pairs (IDT gBlocks) and beyond. Cost has collapsed from about one dollar per base in the early 2000s to a few cents per base today, and Twist Bioscience’s silicon-based platform parallelises thousands of genes on a single wafer. The next frontier is enzymatic synthesis, in which terminal deoxynucleotidyl transferase (TdT) adds natural bases without harsh acid, promising longer, cleaner oligos — the basis of DNA Script’s SYNTAX printer. Because anyone can now order the DNA of dangerous pathogens, the International Gene Synthesis Consortium (IGSC) screens around 80 percent of global commercial gene synthesis against regulated-pathogen sequences.

The key directions of DNA synthesis and the gene foundry are:

  1. Phosphoramidite gene synthesis (Phosphoramidite Gene Synthesis): the established oligo-to-gene-to-clone service chain behind IDT, Twist, GenScript, Eurofins and BGI, delivering genes of a few thousand base pairs in days.
  2. Enzymatic DNA synthesis (Enzymatic DNA Synthesis): template-independent polymerases such as TdT add natural nucleotides in water, the next-generation chemistry behind DNA Script’s SYNTAX printer, promising longer oligos without acid deprotection.
  3. Biofoundry DBTL operations (Biofoundry DBTL): automated Design-Build-Test- Learn loops that turn synthesised genes into assembled constructs and engineered strains (Asimov CAD, Synthace automation, Ginkgo Bioworks foundry).
  4. Sequence-screening biosecurity (Sequence Screening): IGSC and HHS-aligned customer- and sequence-screening protocols that block orders matching regulated- pathogen sequences, the biosecurity gate on the whole industry.

7 · Tech stack & innovations

The gene-synthesis and foundry stack rests on three generations of chemistry plus cloud-coordinated automation, each widening access to written DNA.

  1. Phosphoramidite solid-phase synthesis (Phosphoramidite Synthesis):
    • the four-step cycle (detritylation, coupling, capping, oxidation) adds a base every few minutes on controlled-pore-glass supports, capped near 200 to 300 nucleotides per oligo.
    • genes to about 3000 base pairs are then assembled enzymatically from overlapping oligos (IDT gBlocks) and cloned into vectors.
  2. Silicon-parallelised synthesis (Silicon-Parallelised Synthesis):
    • Twist replaces column synthesis with a silicon micro-well array, writing thousands of oligos per wafer and cutting per-gene cost.
    • the parallel oligo pool is assembled, amplified and verified into clonal genes.
  3. Enzymatic TdT synthesis (Enzymatic TdT Synthesis):
    • engineered terminal deoxynucleotidyl transferase (TdT) adds natural nucleotides in aqueous buffer without acid deprotection, promising longer and cleaner oligos.
    • DNA Script’s SYNTAX printer brings enzymatic synthesis to the benchtop, decentralising gene synthesis.
